SchnuppiLilac You should check if you are all logged in in DeoVR. I have been logged out today. What you are seeing may be the limit for watching free trailers.
It's not that, i can play my purchases and they work perfectly, but also i can play some scenes that aren't purchased that i played fairly recently, but most scenes just have the error.
I also used the Quest 2 brower to login to SLR and the windows for scenes load but missing the text info and showing as 0.00 mins length.
But if i go to my computer and play scenes on Google Chrome, they all work perfectly for me.
Somethings gone wrong server side, probably a quick fix if support see these posts.
I'm also on Quest 2
