TL;DR: Does iOS automatically receive App Store transaction updates in the background when internet connection is available so the backing storage state of Transaction.currentEntitlements gets synced even when my app is not running? Or does iOS update Transaction.currentEntitlements only when my app is running? The long version: Imagine the following situation: A user has purchased a non-consumable IAP in my app and is granted the locked premium content. The IAP transaction is now present in Transaction.currentEntitlements (it's also cached locally). The user blocks internet access every time before my app gets opened (either enables the Airplane mode and/or disconnects from the Wi-Fi before launching my app). So from this point on, my app never gets a chance to connect to the internet. The user gets refunded for the IAP. The user uses their iPhone to browse the internet via Safari, checks emails, etc. Then, before launching my app, the user blocks internet access. My app gets is launched (without internet access) and reads entitlements from Transaction.currentEntitlements. The question is: does the StoreKit service know that the IAP has been refunded? Did iOS update the local cached storage of Transaction.currentEntitlements while the user was connected to the internet in step 4? Or will Transaction.currentEntitlements contain the old state from step 1 so the app won't know about the refund and the user will be able to use my app's premium content which has been refunded by now? Is the behavior the same for auto-renewable subscriptions as it is for non-consumable IAPs?

Hello all! Have open source iOS application. Is it possible to use In-App purchasing (subscription or any other) for donations? Will it be against any kind of Apple rules? The application have no paid content. Just only donations needed. Will it be passing publications checking? This question isn't about using crowd funding or any other kind of platforms. This question about Apple rules exactly.

I have two subscription in the same group and the same level 1. One is a monthly one and the other a yearly one. I also have an IAP for Lifetime Unlock. When my app requests for these it only loads Monthly. Debugging reveals that the ASC doesn't return the yearly subscription and the lifetime IAP. When I added a StoreKit config to the app, it correctly show the Yearly subscription as well and the view loads it appropriately. But the storekit config doesn't load IAP. I have checked things several tiles in ASC and in code. What can I do to fix this?

Hello, We are experiencing an issue with App Store Connect and would like to know if anyone has encountered the same problem. Current status: Our app is already approved and live on the App Store. We created three new auto-renewable subscriptions. All three subscriptions have been stuck in "Waiting for Review" for several days. The subscriptions can no longer be edited (localization and review information are locked). The app review has already been completed, so there is no active app review in progress. During this period, Apple System Status reported an App Store Connect incident affecting submission of In-App Purchases and subscriptions. Since that incident was resolved, the subscriptions are still stuck in Waiting for Review. We have already contacted Apple Support and App Review multiple times but have not yet received any response. Has anyone experienced subscriptions remaining permanently in "Waiting for Review" after the App Store Connect maintenance? Is there anything that can be done from the developer side, or does this require Apple to manually reset the review state? Thank you.

Our app sells two auto-renewable subscriptions. Product loading succeeds and returns both products with correct localized prices, but every purchase attempt fails roughly one second later with "Item Unavailable". No purchase sheet is ever presented to the user. The app has not yet passed its first App Review. It was rejected under Guideline 2.1(b) because the reviewer encountered this same error on their device. MY QUESTION Under what conditions does StoreKit reject a purchase with "Item Unavailable" for a product that has just been returned successfully, with a valid localized price, by a product request? Is an auto-renewable subscription transactable in the sandbox environment for an app that has never had a binary approved by App Review? Question 2 is the one I most need answered. App Review's rejection states that In-App Purchase products "do not need prior approval to function in review", but neither we nor the reviewer can transact them. DIAGNOSTIC LOG Captured on-device during a failing session: 01:08:56 fetchProducts [com.aurascanner.app.pro.weekly, com.aurascanner.app.pro.annual] 01:08:56 fetchProducts -> 2 product(s): com.aurascanner.app.pro.annual=$39.99; com.aurascanner.app.pro.weekly=$6.99 01:08:56 requestPurchase sku=com.aurascanner.app.pro.weekly 01:08:57 purchaseError: code=purchase-error msg=Item Unavailable 01:08:57 error code=purchase-error, storefront=USA 01:09:05 fetchProducts -> 2 product(s), same prices returned again 01:09:05 requestPurchase sku=com.aurascanner.app.pro.annual 01:09:06 requestPurchase threw: Item Unavailable 01:09:06 error code=purchase-error, storefront=USA An introductory-offer eligibility check earlier in the session also succeeded, using the subscription group ID read from the loaded product. So product metadata, including the subscription group, resolves correctly. CONDITIONS Fails identically for both products, on every attempt. Reproduces in TestFlight on our own devices and Apple IDs. Also failed during App Review on iPad Air 11-inch (M3), iPadOS 26.5.2. Storefront reports as USA in every case. Real devices only. Not reproduced on Simulator. ALREADY VERIFIED Paid Applications Agreement: Active, banking and tax information complete. In-App Purchase capability: enabled on the App ID at Certificates, Identifiers & Profiles. Bundle identifier com.aurascanner.app matches the App Store Connect record. Both subscriptions: complete metadata, review screenshots uploaded, USD pricing set, United States availability. Both subscriptions and the subscription group are attached to the current submission, status "Ready for Review". Subscription group has a localized display name. Build distributed via TestFlight, which routes purchases to sandbox automatically. IMPLEMENTATION The app is React Native and uses a wrapper library over StoreKit 2, but the error text originates from StoreKit rather than the wrapper, and the call order follows the documented pattern: Initialize the StoreKit connection. Load products. This succeeds and returns both products. Register transaction update and error listeners. Request the purchase. This is where it fails. Purchases are verified server-side using Apple's App Store Server Library, and the transaction is finished only after verification succeeds. I am not asking anyone to debug the wrapper. My question is about StoreKit and App Store behaviour: what causes the store to quote a product and then decline to sell it? Any pointers appreciated. I can supply screenshots or the full log.

We are implementing StoreKit External Purchase Link for an iOS app distributed in the European Union and are trying to determine whether we are missing a configuration step or encountering a StoreKit server-side eligibility issue. The failure is reproducible in a focused native Swift Xcode project that directly calls StoreKit: let eligible = await ExternalPurchaseCustomLink.isEligible The sample contains no Flutter code, PayPal SDK, networking, or application business logic. Configuration we have verified: The Account Holder accepted the StoreKit External Purchase Link Entitlement Addendum for EU Apps. StoreKit External Purchase Link is enabled and shown as Assigned for the App ID. The regenerated Development provisioning profile contains com.apple.developer.storekit.external-purchase-link = true. The installed app's signed entitlements contain the same value. The application-identifier and team-identifier match the intended App ID and team. The compiled Info.plist contains SKExternalPurchaseCustomLinkRegions with all 27 lowercase EU region codes, including "de". Germany is available for the app in App Store Connect. No local StoreKit Configuration file is enabled. Test environment: Physical iPhone running iOS 26.5.2 (23F84) Xcode 26.6 (17F113) Real German Media & Purchases Apple Account German Sandbox Apple Account StoreKit 2 storefront ID 143443, country code DEU StoreKit 1 also reports country code DEU AppStore.canMakePayments = true AppTransaction verifies in the Sandbox environment Clean build and reinstall using the regenerated Development profile Observed result: ExternalPurchaseCustomLink.isEligible = false For diagnostic purposes only, after observing false eligibility, we also requested both token types: ACQUISITION: StoreKitError.notAvailableInStorefront SERVICES: StoreKitError.notAvailableInStorefront A delayed recheck still reports storefront DEU and isEligible=false. Our production flow does not request tokens unless eligibility is true. We found the similar thread "Unable to enable eligibility for External Purchase Link APIs" (https://developer.apple.com/forums/thread/808349). In that case, the production Media & Purchases account had an unsupported storefront. In our case, both the real Media & Purchases account and the Sandbox account are German, and StoreKit itself reports DEU. We also found "External Purchase in Japan" (https://developer.apple.com/forums/thread/822618), where an Apple App Store Commerce Engineer requested a Feedback Assistant report with a sysdiagnose and screen recording for isEligible=false. Questions: Should ExternalPurchaseCustomLink.isEligible return true in a developer-signed Sandbox build when the entitlement, compiled Info.plist, German storefront, and account conditions are all satisfied, or is TestFlight/App Store approval required? Is there any additional App Store Connect storefront election, entitlement approval, or server-side activation step required beyond the EU addendum, Assigned capability, signed entitlement, and SKExternalPurchaseCustomLinkRegions? If this configuration is complete, could Apple verify whether eligibility has not propagated correctly for the German Development/StoreKit Sandbox environment, and which diagnostics should be included in a Feedback Assistant report? We have also opened a code-level support request and prepared a minimal native Swift reproduction project. Any guidance from StoreKit engineering would be appreciated.

Hi everyone, I'm investigating an issue related to StoreKit 1 receipt validation and would appreciate any insight from Apple engineers or developers who have encountered this before. Environment StoreKit 1 Consumable In-App Purchase iOS 16 / iOS 17 / iOS 18 (observed on multiple versions) Receipt validation performed on our server Receipt is read from the app bundle after the transaction completes Issue Occasionally, after a purchase succeeds and the transaction reaches the SKPaymentTransactionStatePurchased state, the App Receipt exists and can be decoded successfully, but the receipt contains: { "receipt": { ... "in_app": [] } } The in_app array is completely empty. As a result, our server cannot find the purchased product in the receipt and cannot complete receipt validation. Questions I'd like to understand under what circumstances Apple may return an App Receipt where receipt.in_app is empty. Specifically: Is it expected behavior that receipt.in_app can be empty after a successful consumable purchase? Could this happen if the app reads the receipt before the receipt has been updated? Is there any possibility that calling finishTransaction: before reading the receipt could cause the purchase record not to appear in receipt.in_app? If receipt synchronization is delayed, what is Apple's recommended approach? Wait and retry? Issue an SKReceiptRefreshRequest? Or validate using another mechanism? Are there any documented scenarios where Apple intentionally returns an empty in_app array? Additional Information The transaction state is Purchased. The purchase callback is received successfully. We have confirmed that the receipt file exists. The issue occurs only occasionally and cannot be reproduced consistently. Most purchases contain the expected in_app entry. Any clarification about the expected behavior of the App Receipt or recommended best practices would be greatly appreciated. Thank you!

Summary: In Sandbox, Product.products(for:) returns all 3 of my IAPs with correct JPY prices and Japanese localizations, but product.purchase() fails immediately — the payment sheet is never presented — with ASDServerErrorDomain Code=3504 (Product.PurchaseError.productUnavailable). All 3 products fail identically. Reproduction captured in the sysdiagnose attached to FB24067333: 2026-07-30 18:43:58 JST — in-app purchase() on app.negaiboshi.placement; 18:44:40 JST — OS-level test (Settings > Developer > Sandbox Apple Account > Manage > Start Transaction), same product ID. Server correlation keys from the device log: inAppBuy → AMSServerCorrelationKey HNB5UGLE72AXSMY5KY7G4NAXQY (failureType 3504); Start Transaction → FQN4Y4JOEHYBW2GIR7KPTYTB2A (AMSServerErrorCode 3766, "provided product ID or bundle ID is invalid"). Environment App: Negaiboshi — Apple ID 6794682125, Bundle ID app.negaiboshi, Team 778QPP83C4 App status: first submission in preparation (never reviewed); build 1.0 (1) on TestFlight IAPs (all "Ready to Submit" since 2026-07-27 JST, attached to the 1.0 submission): app.negaiboshi.pro.monthly (auto-renewable, ¥480, group 22264517), app.negaiboshi.placement (non-consumable, ¥720), app.negaiboshi.nightsky (non-consumable, ¥1,200) IAP base country: Japan (JPY); availability 145/175 countries Device: iPhone, iOS 26.5.2; development build from Xcode; StoreKit Configuration = None Sandbox Apple Account: (address in FB24067333), region Japan, no purchase history; signed in under Settings > Developer Storefront.current = JPN. No Screen Time restrictions. Actual error (verbatim): Error Domain=ASDServerErrorDomain Code=3504 "このアイテムは見つかりませんでした。" UserInfo={AMSServerErrorCode=3504, client-environment-type=Sandbox, storefront-country-code=JPN} TN3186 checklist fully verified, none apply (Paid Apps Agreement, banking, tax all active; bundle ID + IAP capability; signing; membership). Also tried: Sandbox sign-out/sign-in, device restart — no change. Consistent across all 3 products and relaunches. Reproduced with zero app code involved (decisive): Settings > Developer > Start Transaction with product ID app.negaiboshi.placement and bundle ID app.negaiboshi fails: "The provided product ID or bundle ID is invalid. [Environment: Sandbox]" — Apple's own OS-level tool, no third-party code. Calibration: a deliberately nonexistent ID (app.negaiboshi.zzz) yields the identical error — the backend treats my real product like a nonexistent one. A price change (¥720→¥700, "now", 2026-07-29) propagated to the sandbox metadata catalog within minutes (products(for:) returned "¥700") — purchase() still 3504. Reverted. A full base-country change (2026-07-30): Japan (¥720) → United States ($4.99) at 15:52 JST — this deletes and recreates the price schedule and is the exact operation that resolved the identical symptom in thread 839557. It propagated to the metadata catalog (auto-converted ¥800 shown in ~20 min), yet purchase() and Start Transaction still failed at 16:10 and 16:55 JST. Reverted to ¥720 at 16:59 JST. Every lever that rewrites the price schedule reaches the metadata catalog but never the commerce/purchase catalog. Timeline: the products reached Ready to Submit hours after the 2026-07-26 15:22–17:58 PDT In-App Purchases outage (Message ID 1000005803), and the failure still reproduces after the 2026-07-29 16:20–19:30 PDT emergency maintenance on In-App Purchases + Advanced Commerce API (messageId 1000005805). Peer reports with the same metadata-vs-commerce-catalog split in the same window: threads 839220, 839441, 839437, 839645, 839557. Questions: Why does purchase() fail server-side with 3504 ("item not found") while products(for:) succeeds for the same IDs in the same JPN storefront? Can someone check the sandbox commerce-catalog state of the 3 product IDs above (Apple ID 6794682125)? This looks like a server-side provisioning failure that no developer-side action can repair. Is any additional App Store Connect state required before sandbox purchases can complete for a never-yet-reviewed app?

Summary Sandbox purchases of our first auto-renewable subscription fail with "This item cannot be found". Product metadata loads correctly, so this looks specific to commerce. Our App Store Connect configuration is complete and has been verified exhaustively, and four other apps on the same team sell in-app purchases in production without issue. The affected app has never been submitted or released, and the subscription sits in "Ready to Submit". Symptoms On device (TestFlight build, purchasing with the tester's real Apple Account - no sandbox Apple Account is configured, per the documented TestFlight flow), a purchase attempt returns storeProductNotAvailable and the system alert "Item Unavailable". Device logs (idevicesyslog) show: mzstorekit-sb.itunes.apple.com/inApps/v2/history -> HTTP 404, (4040004) App not found sandbox.itunes.apple.com/.../inAppBuy -> AMSErrorDomain 305, AMSServerErrorCode=3504, "This item cannot be found" Product.products(for:) returns the product and the paywall renders product.displayPrice, so product metadata resolves. Only the purchase fails. Server-side observation Using the App Store Server API in the sandbox environment with our team key, requesting a deliberately non-existent transaction ID: GET https://api.storekit-sandbox.itunes.apple.com/inApps/v1/history/1234567890 App Products Released? Result The affected app 1 subscription, Ready to Submit never HTTP 401, empty body Another app, same team non-consumable, Approved yes 404 4040010 Transaction id not found Another app, same team 2 non-consumables, Approved yes 404 4040010 Transaction id not found Another app, same team 2 non-consumables, Approved yes 404 4040010 Transaction id not found Another app, same team non-consumable, Approved yes 404 4040010 Transaction id not found Same key, same issuer, same team, same request shape - only the bid claim differs. We note openly that this is not a clean experiment: all four comparison apps differ from the affected app in two ways at once (they are released, and they have approved products), so the 401 may simply reflect an app with no approved commerce products rather than a missing app record. We include it because the difference is stark and reproducible, not because we think it is conclusive. What makes this app different Being unreleased does not by itself appear to be the barrier: we were able to test the in-app purchases of the four apps above in the sandbox before those apps were released. The difference we cannot account for is product type and approval state - those were one-time non-consumables, whereas this is our first auto-renewable subscription, which App Store Connect tells us "must be submitted with a new app version" and which has therefore never been approved. Timeline 2026-07-30 ~00:30 CEST - Pricing and Availability set for the app (it had been unset; that was the cause of an earlier, separate failure). 2026-07-30 09:26 CEST - captured the device logs above. 2026-07-31 00:50 CEST - toggled a territory's availability off and back on to force a re-propagation of the availability record. No change. 2026-07-31 - still failing 24+ hours on. Automated probes every 30 minutes throughout have returned the same result without exception. This is well beyond the "up to 1 hour" propagation window documented in TN3186. Already verified Account level - four other apps on this same team currently sell in-app purchases in production: Paid Apps agreement: Active Banking and tax information: complete and active App Store Connect configuration for the affected app: App availability: 175 of 175 territories, none excluded Subscription availability: 175 of 175 territories Subscription priced in all 175 territories Four localizations and the review screenshot present; group localized; subscription state Ready to Submit App price: Free Every territory reads CANNOT_SELL / AVAILABLE_FOR_SALE_UNRELEASED_APP, consistent with an app that has not yet been released Client / build: Product ID in code matches App Store Connect exactly Explicit App ID (no wildcard), In-App Purchase capability enabled Build signed with Apple Distribution, delivered via Transporter, tested from TestFlight (not a development build) No StoreKit configuration file active in the scheme Bundle ID matches the App Store Connect record Questions Is the subscription provisioned for commerce in the sandbox environment? The (4040004) App not found response suggests the app or its commerce record is not present there. TN3186 states that sandbox testing does not require submitting in-app purchases for review. Does that hold for an app's first auto-renewable subscription, given that such a subscription must be submitted alongside an app version and so cannot reach an approved state beforehand? If submitting the app version together with the subscription is in fact the prerequisite, please confirm - we are currently holding our submission specifically so we can complete one successful sandbox purchase first, since App Review purchases through this same environment. If that ordering is not possible, we would rather submit and have App Review encounter the working production path than keep waiting on a sandbox purchase that cannot succeed. Happy to provide the app's Apple ID and product identifier privately if that helps.

I have 2 iOS app products. One can fetch subscription product information normally, while the other fails with the error errorCode 4040004 'App not found' in Sandbox. The App Store Connect backend configuration should be fine, and the subscription code on the app side is the same codebase for both. I really can't find the root cause anymore — if anyone knows what's going on, please point me in the right direction. Also, I'm able to sync/download the StoreKit product configuration file from App Store Connect directly in Xcode, which should also confirm that my App Store Connect backend configuration is correct.

Hello Applet, I’m experiencing an issue with StoreKit on a TestFlight build. My app uses auto-renewable subscriptions through StoreKit and RevenueCat. Configuration already verified: App installed through TestFlight (not debug). Bundle Identifier: com.ciborgu.vytalai Paid Applications agreement is active. In-App Purchase capability is enabled. Three auto-renewable subscriptions exist in App Store Connect. Product IDs match exactly between App Store Connect, RevenueCat and the application. RevenueCat initializes successfully. A Sandbox test account has been created. Tested on a physical iPhone. Device restarted and app reinstalled from TestFlight. VPN and iCloud Private Relay disabled. When attempting to purchase a subscription, the Apple payment sheet never appears. Our diagnostics indicate that StoreKit does not return any available products for the configured Product IDs, preventing the purchase sheet from opening. Expected Product IDs: vytalai_premium_monthly vytalai_premium_yearly vytalai_premium_yearly_intro Could you please verify if there is any issue with the App Store Connect configuration, StoreKit availability, or the processing state of these subscriptions on Apple’s side? If additional logs or diagnostics are required, I can provide them. Thank you. I have already contacted Apple Developer Support regarding this same issue. Previously, I was advised to schedule a technical support meeting. However, when I requested the meeting, my request was declined because of the subject of my issue, so I was unable to speak with an Apple engineer. Since I have now completed all the recommended troubleshooting and the issue still persists, I would greatly appreciate it if this case could be reviewed by the appropriate technical team or a StoreKit engineer. Thank you for your assistance.

Need to vent a bit before relaxing for Christmas... WatchOS IAP using Storekit 2 is such a mess...is nobody actually using this or does Apple just not care for the user experience here? Lots of users experience after the purchase confirmation double tap on the side button an instant return to the purchase screen with nothing actually happening. No error message whatsoever. There is just one remedy: users need to unpair and re-pair their watch, including restoring a backup and setting up their wallet again. Nobody really wants to do this, or doesn't believe me and think this is just typical support BS, because their watch is paired and most things just work as they expect. And it turns away a customer, often leaving a bad review. And I can't do anything about it. Other errors in the purchase process are reported, but like "process interrupted" in case the payment is not setup correctly (credit car no longer valid or sth.). How should the user know? There must be better ways of letting him know what exactly the problem is. You need to implement a "Restore Purchase" function, otherwise you're not passing the review. But it really asks every time for the AppStore password, and users with crazy passwords -- that they rightfully should have! -- have almost no chance of typing them successfully on the tiny AW keyboard. Why is it not also just a side button double tap like for purchase? At the very least you would need access to the keychain PWs or allow pasting of sth. copied on the paired iPhone. Promo Codes for IAP on AW-only apps just don't work. AW has no redemption at all, and on the iPhone the AppStore will try to talk to a companion app (which AW-only doesn't have) and the end up in a dead-end installation effort. This all feels like never really tested in the field, and people are of course blaming the 3rd party dev. for all these issues. And opening a ticket is just leading nowhere -- at best it's closed after months with the hint "duplicate" but w/o any chance for me to see that one that they then actually work on and track progress. It's all so frustratingly broken...

Hello, I'm developing a consumer iOS app (Capacitor + RevenueCat SDK) and I've been blocked for several weeks on a StoreKit issue: subscription products are never returned to the device, so the Apple payment sheet cannot open. I previously contacted Apple Support. I was told to request a phone call, but my call request was declined because of the topic (StoreKit / in-app purchases). I'm posting here hoping someone from Apple or the community can help. App details App name: Vytal AI Bundle ID: com.ciborgu.vytalai App Store Connect App ID: 6767160542 Team ID: JZF7CR3W8Z Distribution: TestFlight (physical iPhone, France) iOS deployment target: 15+ Subscription product IDs (auto-renewable) vytalai_premium_monthly vytalai_premium_yearly vytalai_premium_yearly_intro All three are in subscription group "Vytal AI" on the correct ASC app (not a typo bundle). Cleared for Sale is ON. Paid Apps Agreement is active. In-App Purchase capability is enabled on the App ID (checkbox is grayed out / locked, which I understand is normal). Problem On a real device via TestFlight: RevenueCat SDK configures successfully (public iOS API key present in build). Purchases.getProducts({ productIdentifiers: [...] }) returns { products: [] } — zero products. Because StoreKit returns an empty array, the Sandbox payment sheet never appears when the user taps Subscribe. This is NOT a UI issue — the native SDK call to Apple returns no products. What I've already verified Bundle ID in signed IPA matches ASC app: com.ciborgu.vytalai Subscriptions exist only on the correct app (not on an old typo bundle com.ciborgue.vytalai) Removed duplicate ASC app; old App ID cannot be deleted ("in use by App Store") but has no IAPs Regenerated EAS provisioning profile for com.ciborgu.vytalai Sandbox tester account configured on device (Settings → App Store → Sandbox Account) Tested without VPN / iCloud Private Relay Reinstalled app from TestFlight after ASC changes Waited for propagation after metadata / availability updates Associated Domains enabled (for deep links) — separate from IAP SDK / integration @revenuecat/purchases-capacitor 13.x Direct StoreKit fetch via Purchases.getProducts() (not only RevenueCat offerings) Same result: 0 products from Apple Expected vs actual Expected: StoreKit returns 3 subscription products in Sandbox; payment sheet opens on purchase. Actual: products array is always empty; no payment sheet. Questions Why would StoreKit return 0 products for valid auto-renewable subscriptions on TestFlight when metadata is "Waiting for Review" / in review — shouldn't Sandbox still return products per TN3186? Is there an ASC configuration state (availability, subscription group localization, missing review screenshot on yearly products, etc.) that causes StoreKit to return zero products even in Sandbox? Is there an internal flag or propagation delay on Apple's side I should ask to be reset for this app/bundle? I'm happy to provide additional logs, a sysdiagnose, or a short screen recording from TestFlight showing the empty product response. Thank you for any guidance — this is blocking App Review (Guideline 2.1) and I cannot test IAP at all. Nathan

Hi, Feedback: FB23494579 Using StoreView / ProductView on iOS 27.0 simulator / device hub throws the following error: Error: Accessing State<ProductViewEventConfiguration>'s value without being installed on a View.

Hi, I’m testing an iOS app with auto-renewable subscriptions in the Apple sandbox environment. The app has its own account system. A user can create/log in with different accounts inside the app. The issue I’m seeing is this: I subscribe to the Pro plan using one sandbox Apple ID. Then I log out of the app. I create or log in with a different account inside the app, but still on the same iPhone / same sandbox Apple ID. Inside the app, this new app account is not marked as subscribed. When I try to subscribe again, StoreKit returns: “Item already owned” So Apple recognizes that the Apple ID already owns the subscription, but our app account does not have Pro access yet. The only way to resolve this is to provide a “Restore Purchase” option, so the current app account can restore the subscription already owned by the Apple ID. My questions are: Is this expected behavior for auto-renewable subscriptions? Can this happen in production too, or is it mainly a sandbox behavior? If a user has multiple accounts inside the app but uses the same Apple ID, is the subscription considered owned by the Apple ID and restorable across those app accounts? Is it acceptable/recommended to keep a small “Already subscribed? Restore purchase” option visible on the paywall at all times? If the app wants to prevent the same Apple subscription from being used across multiple internal app accounts, what is the recommended approach? For brand new Apple IDs that have never subscribed before, the normal purchase flow works correctly. Thank you.

Could you help clarify the expected behavior in downgrade scenarios during a Free Trial period? Does Apple trigger billing immediately for the downgraded plan, or does the change take effect only after the Free Trial window completes?

I am experiencing an issue with a non-consumable in-app purchase in my iOS app. The product loads correctly from the App Store and is displayed in the app, but when attempting to complete the purchase, StoreKit returns the following error: Payment completed with error: Error Domain=ASDServerErrorDomain Code=3504 "This item cannot be found." UserInfo={ NSLocalizedFailureReason=This item cannot be found., AMSServerErrorCode=3504, client-environment-type=Sandbox, storefront-country-code=USA } The same issue was also encountered by the App Review tester when they attempted to purchase the non-consumable product during review. The product: Is correctly configured in App Store Connect Has active pricing Is available in the United States Was included in the app submission Loads successfully and displays the correct price Fails only when the purchase is initiated Since the product metadata can be retrieved successfully, but the transaction fails with “This item cannot be found,” this appears to be a possible inconsistency between the StoreKit product catalog and the purchase backend. Has anyone encountered ASDServerErrorDomain Code=3504 for a non-consumable product that loads correctly but cannot be purchased? Is there any known App Store sandbox or commerce backend issue that can cause this, or any additional App Store Connect configuration that should be checked?

App Store Server Notification returns successful purchase while customer's payment remains Pending We have encountered an edge case with a Non-Renewing Subscription and would appreciate clarification on the expected developer behavior. Steps to reproduce User initiates an in-app purchase using a credit card. The purchase succeeds in the app. Our backend receives an App Store Server Notification V2 (ONE_TIME_CHARGE). We successfully verify the signed JWS transaction. The same transaction is also returned by the App Store Server API. Based on the verified transaction, we grant the user's entitlement. However, on the customer's Apple account: The purchase is shown as Pending in Purchase History / Report a Problem. The customer reports that their credit card has not yet been charged. Question From a developer's perspective, should entitlement be granted immediately after receiving a valid App Store Server Notification and successfully verifying the transaction, even if the customer's purchase is still shown as Pending? Is there any App Store Server API or transaction field that indicates the payment has not yet been settled, allowing developers to delay granting entitlement until the payment is finalized? Or is the expected implementation to grant entitlement upon successful transaction verification and revoke it only if Apple later sends a refund notification? Any clarification on the expected workflow would be greatly appreciated. Thanks in advance. :)

Hello Apple Developer Support / StoreKit team, I am testing auto-renewable subscriptions on a real iPhone device using Settings > Developer > Sandbox Apple Account > Test Transactions. I found that subscriptions work correctly for one of my apps, but fail for another app under the same Apple Developer account. Working app Bundle ID: com.benbendou.pinyincharacter Product ID: xpyxhz.quarterly Result: The sandbox purchase sheet appears and the subscription flow can be completed successfully. Failing app Bundle ID: com.benbendou.chengyudaquan Product ID: cydq.quarterly Result: The Test Transactions flow fails. In my app, Product.products(for:) can load some subscription products successfully. However, when trying to purchase cydq.quarterly, the purchase fails with: errorCode = 4040004 errorMessage = "App not found. Please try again." Because the same issue also happens in iPhone Settings > Developer > Sandbox Apple Account > Test Transactions, using the exact Bundle ID and Product ID, this does not seem to be caused by my app’s StoreKit code. The strange part is that another app under the same developer account works correctly with Test Transactions, but this app does not. Could Apple please help check whether the Bundle ID / app record / subscription group / in-app purchase products for com.benbendou.chengyudaquan are correctly linked in the StoreKit Sandbox backend? It looks like the sandbox environment can load the product metadata, but cannot complete the purchase or find the app during transaction lookup. Thank you.
