About ¼ of our users’ attempted subscription purchases on iOS are failing with errorcode 2 (store problem). There are no underlying errors that we can see, but this error message in the logs is present for almost all of them (PID is different each time):
Product purchase for 'pro_plan_quarterly_24' failed with error: systemError(Error Domain=NSCocoaErrorDomain Code=4097 "connection to service with pid 13290 named com.apple.storekitd" UserInfo={NSDebugDescription=connection to service with pid 13290 named com.apple.storekitd})We’ve found this difficult to reproduce on our own devices. We’ve found that when it does happen, then if we press the button to start the subscription purchase again then it does usually work the second time.
Our integration involves AppsFlyer, Superwall, and Amplitude.
We put in additional logging to try to catch whatever the problem is. Since then we are seeing this happening across iOS 18.3.1 and 18.1.1, but it’s happened on other versions before then.
