iPhone XR. Music is coming from iTunes via my library. I've experimented with content both from my main playlist (~4500 songs) and several shorter playlists, to no avail. However, as I mentioned, if I just pick an Album or a specific Artist, I can navigate using the playlist feature.
Even then, it's kind of lame, as there's no indication in either case of which song is currently playing, no album art on the playlist screen, etc.
