(Tested on the rotation around player build you uploaded)
I tried a joy con with this build. I paired my left joycon before I started everything up and it correctly identified it was my left joycon in the driver4vr controller device manager. However the configure button did nothing. Nevertheless I assigned it to the left hand and in game it both failed to rotate my left hand/wand and none of the buttons did anything.
P.s Didn’t occur to me at the time but might it only work if both joycon are assigned?
