Basic operation questions

Can’t find answers to a couple of very basic questions in the user guide.

When playing a track of an album, I can’t directly get back to the album track list after having searched for something or looked at something else. When I select the currently playing track at the bottom of the screen, i get a large photo of the artist. I can select “go to album” from the drop-down menu, but this seems kind of clunky.

How do you swich between 2 zones that are playing concurrently?

There is a back button at the top left that might get you where you want.

Click on the zone icon and you will get a zone list. All zones currently playing will have a little playing bars symbol. Choose the one you want.
