VNAV - I've only done one flight so far and had a lot of issues with vertical profile on descent. It decided to ignore every single altitude constraint, would randomly start showing a massive climb then descent between waypoints, and once drew a flat line past the next waypoint, then back down and left, making a Z shape. I tried changing altitude constraints manually in the FMS but it wouldn't let me enter anything in the text boxes at all.
For liveries, you should expect them to not work or for pink stuff to appear until the livery itself is updated.
