Hi there
We have an app, built for 64bits with IL2CPP for iOS with Fabric (formerly called Crashlytics) and we are receiving some crashed on AppWillTerminate with all version of Unity (we started working on it on 4.6.3). It’s quite strange, because to it seems to happen once the app is killed from background by OS due to memory pressure
Do you know anything?
Regards
Here is the raw of the crash
