I recently picked up a Cosmos so I can get stuck into game development for VR, and have turned on the beta modes, installed the preview packages and updated everything as needed, but I have met with a problem. When I am using the test build everything works great, but when I press play from the editor in the controls sample scene, the HMD is blank. Likewise with the project I am working on. I am using unity 2020.2.4f1. Does anyone know why that might be?
