========================================
I have Niagara, IOS and Microsoft Launchers in addition to ASUS default launchers on mobile.
Post Android 11 update, I have been intermittently (6 out of 10 times) facing issue with the phone asking to select default Launcher (Just Once/Always) whenever I navigate to Home screen.
In Settings - App Defaults - a launcher is already selected as a default.
