AddControllerPitchInput Not Working Specifically in VR

I have the below line in my program:

AddControllerPitchInput(??Direction.X * ??Speed * DeltaTime);

It works great in simulate and play, but not when I use the VR Preview.
What should I check?

I have set bUsePawnControlRotation to true, and that hasn’t done the trick.

Thanks for any help!
