I've noticed a bug with the new app in combination with my Roam SL. On the album page of my streaming service (Deezer in my case), when I hit the play button, in some cases, it will start playing the music in the queue, instead of the album. If I press the play button again, it might start the correct album. I haven't noticed this with any of my other Sonos products.

Added a screenshot to illustrate what button I'm talking about. Circled in red.

Hypothesis: the button calls on two functions. First replace the queue, second start playing the queue. When the first operation fails, the second is still called.
