I used to be able to drag a YouTube link into the part of the site that’s the playlist and it would add. But now I can’t.
I can still drag and drop from a youtube list, but from my personal playlists dragging only works reorganizing the list (and not very well at that). To drag to youtube I have to have the vid on a page instead of inside a playlist.
It’s a YT thing, they messed it up on their end.
Confirming nothing was broken, you can still drag and drop compatible URLs to the playlist area to add them
