Also have the same problem with a pair of bluetooth controllers. Have to remap all the buttons everytime it starts up…. Even once mapped I’ve not had any success in getting the 2 motion controlled games I’ve tried (Pavlov VR, Run of Mydan) past the initial screen they start in.
This problem does not occur if I map up the buttons to my XBone Elite controller….. though it is impractical for tracked motion gaming for obvious reasons.
