Clean my device (or apple id?) from old sandbox users and their subscriptions

This is called ‘the endless loop’. You have Transactions in the queue of that device from that test user. You did not call finishedTransactions on those transactions so they will continue to present themselves sometimes daily sometimes weekly until you call finishTransactions. If you deleted the test user you can’t call finishTransactions. Only Apple technical support can delete such transactions.

If I could clean up such transaction from the test user accounts, I would do so. However this can only be handled by the iTunes Server engineers. They will instead advise you to stop using that test user account, create and use a new test user account.

The problem is that even if I started using a new account, the login dialog pops up for old test accounts. As PBK stated, it could be that there are unfinished transactions (I need to do further investigation on that), but if I understood correctly, I cannot finish transactions of users I deleted, right?

So I contacted iTunes Connect support for doing so and in the future I try to finish also the products that (for whatever reason) have not been finished, yet.

You should delete the app, then clear the iTunes and App Store user setting. Restart the device, then re-install the sandbox app using Xcode. There shouldn't be any user for the transactionObserver to check for incompleteTransactions.

Please try this approach, wait a few days to really test it, then report if it works.

Didn't work :-( Today I got a purchase token (app receipt id) and after server validation "c" did NOT contained the latest receipt info but some *very* old data from May 2017 which must have been from an already deleted sandbox user becuase the one I currently use didn't exist back then.

I even tried to check the receipt data by validating the app receipt id stored in "latest_receipt", but if I query this one I get a 21002 Exception : com.apple.jingle.mzfairplay.validators.DrmInvalidArgumentException.

All in all this is *very* frustrating. Escpecially compared to Android where everything just worked out of the box 😟

Where do this old app receipt ids come from? And how can I ensure to *always* get the latest receipt data?

I expected that. See my earlier post above regarding the endless loop. You most likely failed to call finishTransactions and now you have a zombie transaction from a dead test user. The 21002 means you did not (or did) include an autorenewable password for a receipt with (or without) an autorenewable purchase.

Going to Settings -> iTunes & App Store -> scroll all the way to the botom and you'll see a section called SANDBOX ACCOUNT. The dead user will still be logged in. Log it out. The next time you try to purchase a product, it will prompt you for both an email & password. (iOS 12)

Even if you can't solve it, you can do a couple things that may help somewhat to keep you making progress.

In the func paymentQueue(_ queue: SKPaymentQueue, updatedTransactions transactions: [SKPaymentTransaction]) of your PaymentTransactionObserver as you loop over your transactions, first filter and (try to) finish any old transactions. For example, you could possibly skip transactions before a certain date (though I haven’t needed to filter by date myself).

This could reduce the noise a bit or even a lot depending on your situation. This is obviously a temporary measure so that you aren't blocked.

The other thing that helps is to put a switch somewhere that allows you to simulate in-app purchases during debug. For example, I can turn on and off subscriptions manually during debug. I have a section only present during debug in the table for my settings for things like this. This may or may not be useful depending on your setup. Obviously, make sure the switch is not there in the release version. 😮

For me, it has been really helpful to settle a lot of the peripheral stuff around the UI and various other aspects of being subscribed or not.

And I could narrow my focus as I dealt with in-app purchasing issues.

I tried to finish all transactions in SKPaymentQueue, but after that, I got an endless pop-up to sign-in to old in-app test accounts without knowing what email. Do not test InApp purchase on your own phone, either for fix this issue you should reset data and settings on your phone )))

Apple loves you! Thanks.
