Hi @ab-rdarts,

Does disposing your Firebase instance when quitting the app make any difference?

void OnApplicationQuit(){
    Firebase.FirebaseApp.DefaultInstance.Dispose();    
}

If it doesn't, could you provide a minimal, reproducible example of your implementation so we can identify what's causing the issue?

[ab-rdarts]

No we have no such code, is it necessary for android? We will try to add it in the next version, though as I understand OnApplicationQuit will not be called for mobile applications.
Also we have no minimal reproducible example as we see them only in play console production track. Also we have no such crashes with previous version of firebase (10.0.1) but after upgrading to 11.6.0 we see many of them.

[ab-rdarts]

@paulinon new app version with OnApplicationQuit still has the same crashes

We have the same issue. Any news on this?

[wojciech-juszczynski]

Any updates?

[Bogdan-sybo]

11.7.0 SDK doesn't seem t have this crash.

[wojciech-juszczynski]

@Bogdan-sybo thanks!

[argzdev]

Hi folks, just bumping this thread. Is this issue still present in version 11.9.0?

[google-oss-bot]

Hey @ab-rdarts. We need more information to resolve this issue but there hasn't been an update in 5 weekdays. I'm marking the issue as stale and if there are no new updates in the next 5 days I will close it automatically.

If you have more information that will help us get to the bottom of this, just add a comment!
