I just put up a new update, but there was a serious problem where players made purchases and were deducted, but the game get OnPurchaseFailed event.
Before releasing it I tested it through Test Flight and didn’t get this error.
I’m not sure what the cause is, and it’s still affecting my revenue.

Unity Version
2020.3.41f1
Unity IAP version

Unity Version 2021.3.27f1
Unity IAP 4.8.0

I have same problem since 20 hours ago when I update my unity app.

I’m experiencing the same thing since putting out an update. Just spotted the IAP package is now at 4.9.4 - I’ll try with that installed.
