By using ratio launcher as a default, it can’t allows to use full screen nevigation on Android 10 in stock android phones. It shows “unsupported” and only use 3- button or 2- button navigation
Hi, welcome to the community .
Gestures on 3rd party launchers seems to be a prob of Android 10 as of now. Other launchers (Nova etc) have similar issues. Android 11 is expected to have gesture support for 3rd party launchers though, so we just gotta wait for the OS update.
