Sony Xperia XA2
My Question or Issue
I've noticed I am no longer able to add to or remove from my 'liked songs' playlist. For a song that isn't in the playlist, tapping the heart icon does nothing and no notification is shown. If I find a song that is already in my liked songs and tap the heart icon to remove it, it says 'Removed from Liked Songs' but the icon remains 'filled in' and the song stays in the playlist.
I have already tried uninstalling, restarting, then reinstalling the app.
