I'm stuck at July update, didn't receive any update after that..I had participated in OneUI 8Beta..but even after updating to Stable version I'm still stuck at July update..hence, why I was asking if anyone is already updated to the latest update..??
The issue could be due to MS Team app is still not optimised for the latest version of android, may be you should wait till the app gets updated to the latest version or else try reinstalling the app again.
Try > Uninstall Bud3 Pro Manager from Apps under Settings > Disconnect Buds3 > Connect again > Let it download the Buds3 Pro Manager automatically > Accept All > don't deny any permissions or else it would crash again.
Then go to Device Care > Diagnostics & select the highlighted option from below screenshot to find out which app using more battery...those apps must be consuming the resources the most..
