CloudXR Registering Client position, but no data shown

Hi All, I’m just getting started with CloudXR after a recent demonstration I was shown.

I have gotten to the stage where SteamVR recognises the CloudXR Device (Samsung Galaxy S22 Ultra in this case), but nothing is displaying through the phone once the link is established.

This is true of both the test file in the SDK, and Autodesk VRED. I can see the data moving in relation to my phones movement, but nothing is displaying on the client.

Did I miss something? Thanks
