Interesting how google found a crash on my builds, turned out I was using some very new sqlite statements that weren't supported on Android 11 and below. I noticed some unknown device reporting crashes to firebase on my internal tester builds that I uploaded like 20 minutes ago and no one has access to them except me. I thought, wtf, do I have some virus and attacker already stole my builds??? But from stackoverflow I learned that seems like google is running some automated tests when you upload new apk to internal testing 😅
