ITunes 12.8.0 won't play music videos
Running Sierra 10.12.6/iTunes 12.8.0
When I click play on a music video, I hear the music, but the image on the playbar is just a video still. Doesn't matter whether it's from an Apple Music video playlist, a playlist I created, or a video I've downloaded. There is no "hidden" play window. Miniplayer shows the same video still mentioned above. Tried reinstalling 12.8.0. No help. Tried booting in safe mode. No help.
