[Tutorial] - Ball not moving in Oculus Go

Hi Guys,
Sorry for the basic question. I've followed the "Build your first VR app tutorial" (not able to post the link, even it's Oculus' link due to forum restrictions...) 

In Unity game preview everything works fine and I'm able to move the ball using the arrow keys. However, when running in Oculus Go I'm not able to move the ball.

Perhaps it's how I'm processing the input? Should the touchpad of Oculus controller place the role of the arrow keys? Or do I need to manage the Oculus controller input in a special way?

Thanks.
