iTunes no longer shows current song playing indicator
Recently iTunes no longer shows the current song playing indicator on the left of the song list. It used to have a playing icon next to song name in playlists. Now the only place it has an indicator is in album view.
The thing is it seemed to just stop doing it and not related exactly to an iTunes update. As I checked and there hadn't been an iTunes update for a while when it happened. But its like this now on all my computers. I thought perhaps its a setting, but I can't find anything. I have tried making new users.
I can still see what the current song is by looking at the top of screen where the current song box is. However the indicator in playlists was very handy.
I haven't found any reference to this on the indicator. Has anyone else noticed it missing? Is it a setting, or is it something that was removed by Apple?
Current version of iTunes: 12.7.4, but it was happening before this very latest update.
