Bring up the now playing screen by clicking on the song title in the middle of the bottom command line. Then click on the album cover. That should put you back to the screen with track playing indicator showing.
You can also click on the album cover in the Recently Activity “Played” section of the overview screen.
I have been doing this but needing to constantly re-click a playing album is the problem I am reporting here. It would be great if the software could remember that the album is playing. As the bar at the bottom is updated real time I would expect the information to be available in the software.
