Since recently filtering doesn't work anymore. When I filter a playlist, for example on a specific artist, it will still play all songs from that playlist. I have some very large playlists and used this feature very often to listen only to songs from a specific artist. It is very annoying this is not possible anymore, and I don't understand why such a usefule feature was removed. It does seem to be removed on purpose, as it was already removed from the Android app quite some time ago. Please bring it back!
