Cannot add to Playlists (Android Oreo)


Cannot add to Playlists (Android Oreo)

Casual Listener

Device: Pixel 2XL 

OS: Android 8.0 and 8.1
Issue: Cannot add new tracks to playlist
More detail: When I try to add a new track to any playlist, nothing happens. After frequently tapping on adding to various playlists, it finally shows "Track is already in the playlist" popup. I can confirm that the track wasnt in those playlists before. Also if I dont frequently tap it, then it does not add to the playlist. 

I have tried closing and reopening the app, restarting phone and the issue persists.
