yes but the iReleaseLogger library dont run in the testflight mode from apple, but the error comes only in the testflight mode and in the appstore version.
The message from Apple:
During review, your app crashed on iPhone running iOS 9.3.1 when we attempt to buy the In App Purchase, and after the user confirms they want to make the purchase. Because of the crash, the In App Purchase is never initialized within the app - forcing the users into a loop of buy-crash, buy-crash, buy-crash. The Pro features were never fully unlocked within the app.
We have attached detailed crash logs to help troubleshoot this issue.
