I am building an App with IAP (auto-renewal subscription). The workflow seems to work fine, IPA are created for sure (in iTunes connect), sandbox user also logged in. The IAP product ID is also correct but I get the error (from SKPaymentTransaction):
Error Domain=SKErrorDomain Code=0 "Cannot connect to iTunes Store"
Before that error I get the purchase screens where the price, the duration of the subscription and the name of the subscription is displayed. So the connection and the product ID is correct.
I am logged in with sandbox user: The screens displays [Environment: Sandbox].
I am using a real device (iPhone 7 and iPhone 5). The error occurs on both devices and on simulator (for sure on simulator?).
Any ideas?
I forgot to add localized title and description in iTunes connect. After that the IAP worked like a charm. *doh
