“restore purchases”

A single user can own multiple phones. That single user can download an app and IAPs onto all of their devices. That single user can use the app on the multiple devices at teh same time. All that said - that single user could actually be multiple people - the devices have no way of knowing. But all of the devices will need to be logged into the same iTunes Account at the time of downloading the app and restoring the IAPs. I believe that you cannot restore an IAP purchased under iTunes Account 1 on a device that has downloaded the app under the iTunes Account of a different iTunes Account.I have not investigated whether or not a single user can purchase an app and/or IAPs for that app and then go from device to device logging into their iTunes Account, downloading the app and restoring the IAPs, and then logging out of that iTunes Account.

Same question If the user has purchased the product but it expires, At this point, click restore to buy, Click buy, he will not pop up the Apple Pay page A look at the code shows that Apple is processing the resume purchase order, and if you've only bought it once before, Apple will quickly process it. But I have more than eighty orders and I have to wait for two minutes

Thanks for clarifying your issue.A bit of history. The transactionIdentifier used to be the key to preventing a fairly widespread hack used to steal IAPs. The idea was that you would use a non-unique transactionIdentifier to identify a duplicated signed receipt. With the new receipt system, the lack of a unique transactionIdentifier in signed receipts for both restored transactions and repurchase transactions has made that technique less useful in fereting out the duplicate receipt hack. I was an early complainer and have posted securtity bugs on this matter; but Apple has not responded I assume because they are secure in believing that if a receipt is obtained from [[NSBundle mainBundle] appStoreReceiptURL] it can't be a duplicate. I disagree so I decode on board which is more secure than the Apple server technique. But your concerns are different - you are not worried about fraud.In a receipt after a restoreCompletedTransaction (for a non-consumable or an autoreneawable IAP) or after a re-purchase

I used that logic because according to documentation SKReceiptRefreshRequest is used if the receipt is invalid or MISSING, and restoreCompletedTransactions is used to restore previously purchased IAPs. So is receipt refresh to only be used when the receipt is invalid?Thanks for the answer on in_app!

A user who purchases an IAP will have an original_transaction_id (from the receipt) that will be the same across all devices that download that app and restore that IAP under that user's AppleID. The original_transaction_id is the same as the value for transaction.originalTransaction.transactionIdentifier in a call to updatedTransactions after a restoreCompletedTransactions.

Greetings,I just had this user download my latest App's update that went Ready for Sale, today 12/30/2018 on their new device which implements restoreCompletedTransactions for Restore Subscription, and they got the same result! The exact steps they took were:1. From App they did a Buy of the Auto-renew Subscription, and they received the expected StoreKit's pop ups, that confirm the purchase and ended with You're All Set.2. The Receipt Validation did NOT unlock content.3. They press Restore Subsubscription button that executes restoreCompletedTransaction method to refresh-on a new device.4. Their Receipt Validation still did NOT unlock content. I suspect the Latest Receipt's transaction's 1708 field must not be present for this user, why????5. User then checks the new device's Setting, ITunes & App Store, View Apple ID, Subscriptions, Your Subscriptions-Options and confirms Auto-Renew Subscription they just purchased was completed succesfully and is Checkmarked.6. Then
