Hi everyone!
I just started develop app for oculus quest.
Builded and run, but my app worked just like a photo (attached file)
Build completed with a result of 'Succeeded'

I put OVRCameraRig and a cube. I deleted default camera ,of course.
OVRManager's target devise is quest.
XR Setting> VR suppot checked
VR SDK is oculus

Unity 2018.4.15f1
Installed Android SDK: Android 5.0 to 10.0
minimum API : Android 4.4 KitKat
