loadscene and VR headset

Hi,
Sorry for my english.

I make a project for VR headset and there's a problem with the loadscene() command for headset VR (Pico and oculus Go).
When i start the app in a desktop (Windows, firefox) there's no problem, i can change scene.
When i start the app on a headset in browser mode it's work, i start the enter VR mode it's work, but when i want to go to another scene with a loadscene() command the screen become white without hotspot or anythingelse !!!
Here you can find a simple scene with 2 pano and a hotspot : https://www.kairosguide.com/Test/
Here is my final project with the same probleme : https://www.kairosguide.com/Immersion2/
THX

Thx for your test.
Yes the other pano is loaded by the XXieme siecle button and the blur effect when you click on a hotspot is an other pano too (the blur effect need too much ressource).
I think i will stop the sound when you leave the thumbnails.

Is there other people who test with a pico ?

Always the same problem with another project, is there an official bug Klaus ?

Ok, it works with 1.20 but not with 1.20.9 or 1.20.11 ???
