I couldn't figure out how to label this issue, so I've labeled it for a human to triage. Hang tight.

Hi @pavel-zaletski, have you had any luck reproducing this locally since opening the issue? Apple's Finding Zombies guide may be helpful when trying to reproduce as the toolshould surface which object is receiving messages after deallocation. Another application state to try and target is sending a request before backgrounding the app.

Hey @pavel-zaletski. 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!

Hi @ncooke3, unfortunately I was not able to reproduce it locally. We see this crash only in the Embrace tool on some of our users' devices. I will try to use XCode Instruments tool (Finding Zombies) as you suggested. Thanks.
