I have been complaining about this for ages, and it never seems to get fixed - but I have an update on it which might help the devs
My problem : I progress through a bunch of videos tagged to the "watch later" playlist. THe trouble is, after a few videos DeoVR gets confused, and I am no longer looking through the "Watch later" playlist, but appear to be watching "New" videos (as in the ones that appear in the New category). I then have to navigate back to the "watch later" playlist
What makes it confusing is typically my "Watch later" videos are also fairly recent, so will be in the "New" category so its not clear to me when DeoVR gets confused - just that it happens OFTEN
I now feel the core issue is a sort of latency/sync issue between the DeoVR app and the server - so you remove something from watch later, then resume watching - and somehow the server gets the update, then pushes it back to DeoVR confusing the player between what is/isnt on the playlist
Anyway its been bugging me for ages so I hope this is useful
