To fix the pop-up issue, go to Settings -> App preference, and disable "Allow pop-up messages". To the managers of the developers of the Sonos app... you are bad people for forcing people to have to close pop ups so that the people that already gave you $2000 can do something like change volume on a device. The latest update turned on the pop up ads by default. Judging by all the other reviews, you would be wise to turn that back off.
