That's not all, there are some channels where you can't even sort by most popular anymore.
From what I gather they're mostly music-related ones (perhaps in favour of YouTube's "most popular songs" playlists). Here's a random example: https://youtube.com/c/DomDolla/videos
Notice there's no option to even select any type of sort.
It makes a tiny bit of sense to use that YouTube playlist instead (for example artists may upload songs to a label's channel or something), but it's still very annoying.
