Gear VR HMDTouchPad not working

I followed this tutorial: https://docs.unrealengine.com/en-us/…To/HMDTouchPad , in fact, I used the example project provided, but when I use the HMDTouchPad all I see is “TEMP TEMP TEMP”. I tried creating a new game mode with GearVR_Pawn as the default Pawn class but it didn’t work either. What am I missing? Thank you.

EDIT
I know that the touchpad is not at fault, because when I press the home button I can use the touchpad, but when I resume to the game it doesn’t work. Please help!
