Does your choosen Oculus home environment is now replaced by a gray generic background and you can't find a way to actually change it back ?
Previously, you could change the home screen background in
Environments tab in the left menu, but this menu does not seems to be there anymore...
Still in the library page, there is a message above apps list saying what environments have been moved to
Parameters but when I go there, I see no environments settings ! There is a
See all button on the far right, but when I click it, nothing happens...
TL;DR : So, the solution is to re-do the tutorial located at the bottom of
Library tab's left menu. And don't skip it until you've reached the part where you can choose the background ! When it's done, save it and your background will be there ! (even after you reboot the device)
NOTE : this will not actually fix the fact that there is no environment menu anymore, but I feel like it's a bug that will be fixed eventually by oculus... will update this post when things changes.
