When I look in the web console I see the following errors
To Reproduce Steps to reproduce the behavior:
- Start Quest Link
- Go to https://de-panther.github.io/unity-webxr-export/Build

Expected behavior it should load the scene as per the web page?
Screenshots I see a spinning hour glass in the headset.

Are other WebXR Samples (non-unity) don't work on your device? https://immersive-web.github.io/webxr-samples/immersive-vr-session.html
https://immersive-web.github.io/webxr-samples/immersive-hands.html
If so, It might be an issue with OpenXR or browser on your device.
Hi both of those samples load successfully. The hands demo is a bit messed up as I see some black hand models not oriented correctly and not made out of cubes.
Your demo still hangs.
I closed chrome and reopened it. I went to your demo page first and it loaded this time. Thanks for your help debugging this issue.
Any suggestion on how to investigate for these errors
WebGL: INVALID_OPERATION: readBuffer: invalid read buffer WebGL: INVALID_FRAMEBUFFER_OPERATION: drawElements: Cannot render to a XRWebGLLayer framebuffer outside of an XRSession animation frame callback.
Warnings. And no. It happens on the frame that switch between non-XR to XR mode. Doesn't affect performance or anything else.
I am a little confused. My assumption was my app isn’t loading because of those errors. Do you have any suggestions on how I can debug why I get the hourglass and my app is not loading?
Those are warnings, not errors. The app isn't loading because of a bug in Chromium or OpenXR. Try to open 2 tabs of the non-Unity WebXR Samples and enter VR. It won't work.
When I reload the browser and enter your demo app it works. When I reload the browser and open my app it hangs. I would like to determine why.
Is your project works on the Meta Quest Browser?
It loads but the headset is not tracking properly.
In WebXR on the PC using the Immersive web emulator, I see double vision and the headset is not tracking properly.
In an older version of the project using Unity WebXR export .14 it was working okay. I upgraded the project to .22 but did not change any of the WebXR components already in the scene.
To give you an update, I reverted back to 0.14.0-preview and our scene started working again. Is there a migration guide for moving from earlier versions of WebXR to the latest version?
Look at the latests Getting Started guides in the repo (the basic one and the xr interaction toolkit one). They were updated recently.
If you are using latest XR Camera Rig prefab, the URP one needs XR Display Submodule to be enabled, and the BiRP one needs it to be disabled. There are notes about it in the guides.
