Last week my webXr augmebted reality seems have bug not related to my code:
After few seconds in AR mode, the camera seems turn left of 90°.
Tested on Android, Chrome and different smartphone.

Any suggestion to fix it?

I can reproduce the issue. When starting the demo, the camera has a wrong orientation (the actual scene is on the left side). After a few seconds, the camera changes to the correct orientation and everything is in view. It is necessary to move the phone a bit around though.

Looks like a bug to me. It also seems the issue has not been reported at the Chromium bug tracker, yet.

Great! Do you mind sharing the link to the bug in this topic?

Do you mind showing with code what you are doing? What exactly does not work?

I can reproduce this issue as well. It seems to be getViewerPose() in the animation frame callback returning a rotated pose. Interestingly it doesn’t seem to be reproducible in Model-Viewer which I think uses the same code path…
