New app shows content and system but have to go to computer to play anything

Hello,

     as everyone did allowed the app to update on my phone,  no advanced usage just turn on music to play.  I see all my play lists, for some reason it always defaults to my bedroom where early in the morning on the weekends when i try to get things done is not where i want to play music.  Then i press the button to play.. NOTHING… have to go to the computer app to get anything to play to my sonos system..   This was a simple app through the past updates any advise??
