x88 Max+ Android Hide On Screen Keyboard This little box is so close to replacing my PC but it has a number of frustrating issues that I would like to fix (it's running Android 9.0).

The on screen keyboard won't go away. I have show virtual keyboard turned off in physical keyboard settings but it still appears.

The enter key enters the currently selected key on the physical keyboard instead of enter. I know how to fix this by rooting the device but I don't know how to root the device (and I'd rather not root the device if I can avoid it).

The cursor keys control the selected key on the on screen keyboard instead of the cursor position on the screen.

Selecting a suggested search term in Google Chrome with the mouse while typing in the URL/Search bar doesn't work (does nothing).

If I can fix the on screen keyboard issues this box will be good enough to replace my PC! Any help appreciated.
You can use External Keyboard Helper Pro app to do this on the T95Q, I assume on the X88 MAX Plus too (I got rid of mine as it cannot do VPN over Ethernet).
