(iPhone XS Max)
I have run into this a bunch of times and don't know why it wasn't an issue before which makes me think it's a bug?
I've had various playlists of mine add to my queue without my doing (100+ songs) and then if I want to stop the entire playlist from playing I then have to delete 100+ songs by tapping every one? I don't know how these playlists are automatically adding to my queue, but without the ability to mass delete my now stacked queue would take so long to erase!
Implementing such an easy alternative would solve this problem, whether it's actually a bug or me adding whole playlists to my queue and totally forgetting I did it. I can't even add songs to the front of the queue because the whole playlist is in front of it - I have to press every new song as the current one ends. The only way I've been able to fix it is by deleting the app and just reinstalling/signing in.
