My Question or Issue

I "like" an entire album (which I gather adds it to my Library), then I "unlike" certain songs on that album which I do not want to be played back in the future. However on my phone it continutes to play those songs - even when I explicitly go to Your Library / Albums, choose the album, and start playing it.

This does not occur on the desktop app; there, it does not display or play those "unliked" songs - the expected behavior.

I must be missing something? The ability to delete (or at least skip playback of) certain songs from an album in the Library on one's phone seems very fundamental. Thanks
