I'm also having issues with crash reports since about a month. I have one user on iOS 14.6 that manages to crash my app every time it launches. He runs the newest TF version of the app. However none of his crashes are ever sent to App Store Connect (nor available in Xcode). He doesn’t get any popups asking whether he wants to send crash data. He has “Share with App Developers” enabled in Settings -> Privacy -> Analytics and Improvements. Any idea why his crashes aren’t sent?
The latest crash I see in App Store Connect is from 16th of June and there have been crashes since that based on discussions with users.
Is the best way to again start relying on some third party crash reporting tool, as Apple's stuff clearly isn't working out? I used Crashlytics in the past before Google ruined them and it was awesome, but is sadly not an option anymore.
