There are many place where the UI is inconsistent, or buttons that you can't navigate or click except with a mouse (example: the join button in the multiplayer section). I understand that it might not be an issue to many, but if you use AMS2 primarily with VR it is in an important feature. Adding to this, many parts in the UI are weird, like if you have 2 buttons side to side you can't use the right pad to navigate to it, but push the down button instead.
I second these. Also selecting a livery - as far as I can tell, using buttons on a wheel, you can enter the livery selection screen but not actually select one without using the mouse.
