Until yesterday I could run WebVR and WebXR Playgrounds in my Oculus Qest.
Today all of them start fine in 2D. But starting the immersive mode,
I just see the lilac background, no objects in any example playground.
(May be there are log outputs but I don’t know how to see them)
I did not see any updates for the Quest system or its browser, but you never know.
Only the playgrouns, my own tests on my browser still runs normal:
