I was checking my controller mappings in VR recently, and while the key assignments screen was being displayed, I used the double-tap pass through view of the Quest to see if I could read button labels on my controllers, but when I double-tapped back into the game, all my controller settings for both the throttle and joystick were wiped out. My pedals settings were unaffected.
I was able to restore from a copy of the .jsm files I had, but still its something to be aware of...
