Google Play Games Leaderboards Submit Score doesn't work on Android 11 devices

Our project uses Google Play Games Leaderboards - leaderboard score viewing and submission works on Android versions less than 11. On Android 11, only view leaderboard scores work - score submission fails (no visible error in adb logical). In case we were doing something wrong, we downloaded “Unreal Match 3” to test as well.
