How do you clear the queue on the new App

The app was released with some important functions missing, that much is obvious.  Sonos has stated that queue functions will be fixed in early June.

Thank you, but how do you stop an album from playing ?

Tap on Stop in the room where the track is playing.  To switch rooms, swipe up from the room at the bottom of the screen, and choose your room by tapping.

So it just stops the play, I can see that thanks but how do you clear the album from showing at the bottom of the app?

If you are looking to clear the queue entirely, you can’t.  That function is currently missing.  

Work around: 

Open Sonos app on a computer (I have a MacBook). Clear queue. The iPhone app queue will then be cleared as well. 
 

Better than nothing. At least it can be cleared. 

The new app stinks. I have a queue that has glitched and now I can’t clear it or play any music at all now. 😡

Queue management should be in the next fix. They said early June.

Will deleting and reinstalling the app clear the queue? 

No, the queue resides on the players.  You can clear the queue from the PC/Mac controller.
