We are facing a serious issues with in app purchases in our app.
We offer 3 IAP: auto-renewable subscription 1W, auto-renewable subscription 1Y, non-consumable one-time purchase (LifeTime access)
In our case 90-95% of transactions fail and we mostly get SKError code=2 .
Sometime purchase fails several times for the same user so it’s very hard to believe that user intentionally cancels transaction for the same product 4 or even 5 times in a row.
It happens regardless iOS version, device model, our app version.
We've checked multiple threads with the same issue but coudn't find any solution.
We do not offer any promotions, product identifiers are valid... Some users are able to make a purchases without any issues.
