Unexpected Change in Apple Refund Handling CONSUMPTION_REQUEST - Impact on Subscription App with AI Backend
We offer a 3-day free trial, and our paywall clearly states that users will be charged after the trial ends. However, some users request refunds after the charge - even after fully using our app for days or even weeks. In some cases, refunds are approved despite the users having consumed our AI processing services for up to a month. Since our app relies on backend AI processing, each user session incurs a real cost. To prevent losses, we utilize RevenueCat’s CONSUMPTION_REQUEST system and have set our refundPreference to: "2. You prefer that Apple declines the refund". Until recently, Apple typically respected this preference, and 90% of refund requests were declined as intended. However, starting about a week ago, we observed a sudden reversal: Apple is now approving around 90% of refund requests, despite our refund preference. As a result, we are operating at a loss and have had to halt both our marketing campaigns and our 3-day free trial. We’re trying to understand whether this shift is due to a change in Apple’s refund policy, or if we need to handle CONSUMPTION_REQUEST differently on our end. Has anyone else experienced similar changes? Any insights would be greatly appreciated.

Landscape safe area is incorrect when presenting SKStoreProductViewController
Hi. If the app is in landscape only and when the SKStoreProductViewController is presented, the safeArea changes to what looks like a portrait mode safe area. When the SKStoreProductViewController is dismissed, the safeArea does NOT revert back to the original values. Is there a way to force the safeArea to "reset"? I've submitted some bug tickets through Apple Feedback but I haven't received any response about it. The below code will pop up the SKStoreProductViewController and if you have a UIView that is constrained to the safe area, then you can visibly notice that the safe area is changed and doesn't go back. I have tested this on iPhone 14 Pro, iPhone 15, and iPhone 16 Pro and in the Simulators. The incorrect behavior happens on those and probably more. Thanks. #import "ViewController.h" #import <StoreKit/StoreKit.h> @interface ViewController () @property (nonatomic, strong) SKStoreProductViewController *productViewController; @end @implementation ViewController - (IBAction)buttonTapped:(id)sender { self.productViewController = [[SKStoreProductViewController alloc] init]; NSDictionary *parameters = @{ @"id" : @"6443575749" }; [self.productViewController loadProductWithParameters:parameters completionBlock:^(BOOL result, NSError * _Nullable error) { [self presentViewController:self.productViewController animated:YES completion:^{ // presented // The panel that is constraint to the safe area visibly shows that the safe area is no longer correct. }]; }]; } @end

Cannot get public keys for jwks verification
I am using the public url https://api.storekit-sandbox.itunes.apple.com/inApps/v1/notifications/jwsPublicKeys to get the jwks keys to verify the signed payload for store kit payments. I am checking Apple server notifications. const APPLE_JWKS_URL = "https://api.storekit-sandbox.itunes.apple.com/inApps/v1/notifications/jwsPublicKeys" // Apple JWK set (cached by jose) const appleJWKS = createRemoteJWKSet(new URL(APPLE_JWKS_URL)); const jwks = await appleJWKS(); logger.debug("Apple JWKS Keys: %O", jwks); // Log the keys if (!signedPayload) { // return res.status(400).json({ error: "Missing signedPayload" }); } // Step 1: Verify JWS (signature + payload) using Apple's JWKS const { payload, protectedHeader } = await jwtVerify( signedPayload, appleJWKS, { algorithms: ["ES256"], // Apple uses ES256 for signing } );

Unfinished transactions not being emitted on start of app
I'm using the iOS simulator with a StoreKit configuration file. I can see that there have been transactions while the app has been closed, but my StoreKit 2 listener is never called with those updates to be able to finish them When I open my app from a cold start. I've added a listener on application(_:didFinishLaunching:launchOptions:) like this: func startObservingTransactions() { task = Task(priority: .background) { for await result in Transaction.updates { if case .verified(let transaction) = result { await transaction.finish() } } } } But the Transaction.updates loop never gets called (have added breakpoints to check). It's only ever called when a purchase is made, or subsequent transaction renewals when the app is open. Only then it will get the previously unfinished transactions. Steps to reproduce: Create an app with a StoreKit config file (with sped up transactions) to purchase an item Make a purchase then quit the app Wait for a bit for more transactions to be made while the app is closed. Open the app from a cold start and none of the transactions will be finished by the listener in your app. Cancel the subscription via the transaction manager. Close and open the app from a cold start. The first transaction will be finished by the listener but none of the others will be. In Apple's docs it says If your app has unfinished transactions, the listener receives them immediately after the app launches Why is this not the case?

Mac Appstore StoreKit 2 - validate purchase & where is purchase receipt cached?
This is re-posted from this Stack Overflow post. I am looking at validating the purchase of a paid app from Mac AppStore. Based on this WWDC video about StoreKit 2, I am attempting to this with AppTransaction. I have not found meaningful high-level documentation about this specific use case beyond that. My approach is to first get the "cached" AppTransaction by calling AppTransaction.shared. If that is not there I proceed to getting it from Apple, via AppTransaction.refresh(). If they don't have it, or when the network is down, the user automagically gets the familiar "log in to your store account" UI that has been around as long as the Mac AppStore. Once I have the AppTransaction I use it to verify we are on the right device, using code like this, where the returned Bool represents validation success: guard let deviceVID = AppStore.deviceVerificationID?.uuidString.lowercased() else { return false } let nonce = appTransaction.deviceVerificationNonce.uuidString.lowercased() let combo = nonce + deviceVID let digest = SHA384.hash(data: Data(combo.utf8)) return (digest == appTransaction.deviceVerification) My first question is: Does that look like the right approach? Is there something else I should do, or check? My second question is around testing this approach. Refreshing the AppTransaction in the sandbox invariably yields a valid item, even if the app version does not yet exist in AppStoreConnect. This is also the case when I log out in the App Store app on the Mac. This makes me think it is using my AppleID which I am logged into in System Settings. Does that sound right? I would like to be able to remove / delete the cached AppTransactions - where might I find those on the system? Thanks for everyone's help!

StoreKit in IOS 18
I have has a the Storekit working in my application previously. It uses the a iTunes songs ID and allows the user to purchase the track from iTunes within the app using a View. its been fine in IOS 17 but since the update to 18 Ive not been able to get this to work. the iTunes panel loads within the app and shows the track I wish to purchase. on clicking purchase I login with my Apple ID password. that then spins for a few seconds then asks to do the purchase again. Can you please advise. code below print ("Store ID + \(self.appId)") let storeProductViewController = SKStoreProductViewController() storeProductViewController.delegate = self let parameters = [SKStoreProductParameterITunesItemIdentifier: self.appId] storeProductViewController.loadProduct(withParameters: parameters) { status, error -> Void in if status { self.present(storeProductViewController, animated: false, completion: nil) print("success: \(status.description)") } else { if let error = error { print("Error: \(error.localizedDescription)") } } } DispatchQueue.main.async { self.isPresentStoreProduct.wrappedValue = false } }

Failure during payment with sandbox account
I got this error if I buy my IAP on the simulator with a sandbox account. Any solutions?

Mismatch between App Store Server API `expiresDate` (July 23) and iOS UI “Expires on” date (July 22) for 1-month subscription
Hi everyone, I’m seeing a consistent one-day discrepancy between the expiresDate returned by the App Store Server API and the “Expires on” date shown in the iOS Settings / App Store subscription list. I’d like to confirm whether this behavior is expected or if I’m misunderstanding the way Apple rounds dates. Reproduction steps Step Action Result 1 Purchase a 1-month auto-renewable subscription on 23 June 2025 14:00 JST (UTC+9) Transaction succeeds 2 Immediately fetch the transaction with GET /inApps/v1/subscriptions/{transactionId} Response contains "expiresDate": "2025-07-23T05:00:00Z" (= 23 July 2025 14:00 JST) 3 On the same device open Settings › Apple ID › Subscriptions (or App Store › Account › Subscriptions) UI shows Expires on: 22 July 2025 The same happens for every monthly renewal and on multiple devices. Region is Japan, device time zone Asia/Tokyo. What I understand so far (and my hypothesis) Apple’s docs say a monthly subscription renews “on the same calendar date” of the next month, so renewal in this example is 23 July. If the renewal is scheduled for 23 July at 14:00 JST, the subscription is fully usable until the end of 22 July in calendar terms, because the new billing period starts the moment the 23rd begins in Apple’s canonical time zone. Therefore, it might be intentional for the UI to display 22 July—i.e., “you can keep using it through the 22nd; on the 23rd it renews.” This hypothesis makes sense internally, yet it still looks confusing to end users who read “Expires on 22 July” and assume access ends at 00:00 on the 22nd, a whole day earlier than in reality. Questions Is showing the day before the renewal date the official/expected behavior? If so, could Apple clarify that the “Expires on” label represents the last full calendar day rather than the exact expiry timestamp? Which value should we surface in-app when telling users “Your subscription is valid until …”? The server’s expiresDate (precise to the second, converted to user time zone), or A UI-style date that’s one day earlier, matching Settings / App Store? Does Apple have a public document describing this rounding/visual convention? Have other developers encountered user confusion about the apparent 1-day “shortening” and, if so, how did you word your in-app messaging? Any insight from Apple engineers or fellow developers would be greatly appreciated. Thank you!

app signatures do not appear in sandbox
I've been trying to make my app available on the App Store for a month now, but I can't because the signatures I created don't appear in the sandbox app. I did all the configuration in the store and in the app. I tested the same code in another app with signatures and it was loaded, but the signature for that specific app doesn't appear. I've tried contacting Apple support, but they can't help me. It almost seems like it's on purpose. I'm treated like crap and they don't even give me an explanation about what's happening. Can anyone help me?

"purchaseDate" of the Reciepts
I have some questions regarding the specifications of the receipt information that can be obtained from https://developer.apple.com/documentation/appstoreserverapi/get_transaction_info. When a subscription is newly purchased, it is expected that the purchaseDate should reflect the time of purchase and should not be later than this time, such as an hour after the purchase. Is this understanding correct? We observed a phenomenon where, when a user purchased a new subscription between 17:30 and 20:00 JST on November 3, 2024, the purchaseDate in the received receipt was delayed by one hour compared to the actual purchase time. Is this a specification or an issue? When validating the receipt for a newly purchased subscription, if the purchaseDate reflects a time later than when the purchase was made, should I regard the user as having subscription rights at the time of validation?

Recurring subscriptions return with an "Unknown Error" fail message
Testing recurring subscriptions in a new release in both development environment and in Test Flight, we see an increased percentage of failed calls returning from Apple server. The return failure message is that an unknown error occurred. The behavior is not consistent and most often we get a failure and another attempt succeeds. We do get around 50% failures which is alarming and cannot be explained to the end user. We have also experimented with previous test versions that are in production currently and we see the same behavior, so this is not isolated to the most recent release we plan nor to a specific application we have. Past testing in previous releases did not return such high percentage of failures from Apple server. Have you encountered such an issue? We have no idea what may cause Apple server to return with this "Unknown error" and there is no log we can consume from Apple subscription service. Appreciate your help on this.

StoreKit 2 Fails to Load Subscription Products
We are experiencing a critical issue where StoreKit 2 is returning empty products when using Product.products(for:), specifically on devices running iOS 18.4.

 This issue does not occur on iOS 18.3 or earlier.

 Steps:

 Created a subscription product (e.g. "upm1") in App Store Connect
 Confirmed the product is active, localised, and part of a valid subscription group
 Call the following Swift code using StoreKit 2:
 Task { do { let products = try await Product.products(for: ["upm1"]) print(products) } catch { print("Error: (error)") } } 4. Result: products is an empty list.

 This regression is blocking subscription testing on iOS 18.4. 

 Kindly someone please advise on a potential fix or workaround.

Best way to share subscriptions between iOS and watchOS apps
I'm working on a watchOS app that has an iOS counterpart. There will be a subscription required to unlock functionality and I would like the user to be able to make the purchase on either the iPhone or the watch and have both apps unlock. The first link below says that StoreKit 2's Transaction.currentEntitlements will not work in this case like it does with extensions. The second link says it might work but doesn't in the sandbox. What is the best way to make this work? Will it just work in the App Store? Should I use WCSession to send the purchase information from one platform to the other and store it in the keychain? Something else? Via https://www.revenuecat.com/blog/engineering/ios-in-app-subscription-tutorial-with-storekit-2-and-swift/ "Transaction.currentEntitlements can be used in extensions the same way it was used in the previous steps. This works for extensions like Widgets and Intents. However, an iOS app with a companion watchOS app will not work even though Transaction.currentEntitlements can be executed in it. A companion watch app does not stay updated with the same transaction history as its iOS app because they are separate platforms." Via https://developer.apple.com/forums/thread/739963 "In TestFlight I was able to confirm that the Watch app and IOS app share in-app purchases. It seems the problems confirming this with Storekit and Sandbox are limits of the testing environments."

APIs available in Objective-C equivalent to Storekit2
The following document states that some APIs in Storekit1 have been deprecated and that migration to Storekit2 is recommended, but I understand that Storekit2 only supports Swift. I'm currently creating an iPhone app in Objective-C, but is there a way to implement APIs equivalent to Storekit2 using a different Objective-C API? https://developer.apple.com/documentation/ios-ipados-release-notes/ios-ipados-18-release-notes#StoreKit

Handling Empty 'in_app' Attribute in App Store Receipts
We are facing an issue where some users send receipts with an empty 'in_app' attribute during server validation. We are using the API described here: https://developer.apple.com/documentation/appstorereceipts/verifyreceipt After a purchase, we validate the receipt on the server and call finishTransaction in the app. Most receipts are fine, but this issue affects some users. The documentation states that an empty 'in_app' attribute means no valid purchases: https://developer.apple.com/documentation/appstorereceipts/responsebody/receipt/in_app#discussion Our questions are: When is a receipt with an empty 'in_app' attribute generated? How should we handle such receipts? Thank you for your help. Best regards,
