Thank you for the report. We attempted to reproduce your report on multiple devices but we were not able to confirm any issues on our side. All battles could be started and completed without freezes or crashes.
I have the same issue after the last update, Making me lose GAC matches. Waste energy in conquest and lose arena battles. Very frustrating. I also have a Samsung S21
Same problem on Samsung S20. Never had freezes occur in last 2 years until the last update. Frequently freezing. Have cleared cache, applied all latest patches, restarted phone and apps. Still occurring. 4 times yesterday, 3 times today. Lost 2 GAC matchups because of this. Lost 4-5 conquest battles & wasting energy. This is one of the poorest quality releases I've seen.
That's the entire problem. Your testing process sucks. These things happen every release. In technology development there is this thing called "regression testing" which is used to make sure new code doesn't break anything that's already been deployed to users. Having some random dude play test for 5 minutes on an iPad doesn't represent the full scope of game play this game has grown into. These are super basic things with any software development and you continue to fail at them over and over and over again.
