iOS 13 TestFlight not reporting crash, only feedback.json
This happens when the watchdog kills the application due to some reason. we can check the logs in the Analytic & Improvement section
Encountered the same behaviour when the specific device was on low storage. The device has less than 50 MB remaining from 30GB of storage.
I am facing the same issue, the system terminates the network extension due to some reason. And, many users has downloaded the app from test-flight and they are seeing the default crash alert from OS. since test-flight feedback does't contain crash logs, i am not able to identify the problem.
