Hi,
I have been sandbox testing for a while with the same sandbox user. Though when I used another sandbox user I ran into the error “There was an unknown backend error. The subscriber has reached the max number of Apple receipts allowed (7636). Then I cleared all sandbox users purchase history in App Store Connect, but ran into the same error when trying to subscribe with the new user. Though I could make a subscription using the original sandbox tester. My next move was to delete the original sandbox user in App Store Connect, but I still ran in to the same error (7636) when using a new sandbox tester. But the new sandbox users had a subscription, as I could see in App Store on the test device. After reinstalling the app and restoring the new sandbox users subscription the app worked as intended.
So my questions are:
Is the error originating from RevenueCats backend or App Store?
Can you clear the sandbox purchase history in RevenueCat?
I realise it is highly unlikely to run into this problem in production environment, my original sandbox user must have subscribed at least 100 year.
Regards,
Tomas
