I just tried today OVR Scene Quick Preview but it is not working - it looks like bug to me:
1. When I press Build Deploy App it ask me to: “Select at least one Android CPU architecture in Player Settings” and I have selected it as you can see on photo...
Than after press ok OVR automatically uncheck this option!:
It only allows me to build on ARMv7 , which is not working on Oculus Quest...
Did you manage to use OVR Scene Quick Preview on Oculus Quest???
[My setup: Unity 2020.1.0f1 + Oculus Integration Version 18.0 + URP with XR Plug-in ]
