[Oculus GO] VR seems disabled in Unity

Hi,

I have been following the documentation guidelines to prepare my environment for targeting Oculus GO devices.

Went well, until the tutorial "Tutorial: Build Your First VR App" bugs when ran on the device: the view is messed up (as if stereoscopic rendering is broken), and head movements are not tracked. I'm not sure about it but if I reckon correctly, pressing the Home button didn't prompt the "Quit application" dialog.

As soon as I import the Oculus Utilities it fixes every issue. The Oculus Utilities package is tagged as optional, and for simple applications I would like to avoid using it. I also would like to understand what can possibly cause the issue.

What is weird is that I don't even edit my scene after importing (I don't use Oculus prefabs/scripts/etc).

Do someone knows how to fix this (build Oculus Go application without importing Oculus Utilities) ?
