It's funny... I just tried to reduce my 'watch later'-category today and move some off into other playlists, but for me it's only in the browser (I don't login on the DeoVR/SLR app). But can confirm, I too had the same issues.
At some point you just get a server 500 error even though there should be more pages left. For me sometimes page 47, sometimes page 48 would be the last working page. Even though when counting the total result in the json array (from the getList result, webdev will understand) I should have had 62 pages of 24 scenes per page. Deleting/moving scenes from the playlist kept filling up page 47/48 until I had reduced it enough to go under that 47/48 pages limit...
It's really weird page 47/48 is not where it breaks for everyone but it seems is different for each person...? I figured something was fucky with the pagination code as it's easy to go wrong with that but this is all very odd.
I thought it might be a thing with hidden scenes from studios that are gone (VRBangers, VRConk, etc) as those are counted and shown in the playlists, but perhaps some part of the pagination code wants to not-count them and causes a server 500 error? Then again I moved all of those into a new 'wtf-deleted' playlist with 5 pages and the pagination for that works fine so... dunno. (Plz don't hide them from playlists as well btw, that'd be worse imo ).
---Edit: Just tested adding more than 24 "hidden" scenes to watch later playlist and it didn't cause any issues with displaying another full page of that, so maybe that's not what is causing it then... I dunno, it's weird.
