WTF Sonos? You are garbage. Your app is no w complete garbage. Every time i go to use my simple system it's garbage. From not connecting (multiple mesh points with wifi coverage out to 1000’ from y residence), to not even being able to control volume on a device that's whiting 60’ of a primary router and 20’ from a mesh point. 

What does it take to be a software engineer at Sonos, a pulse?

If so, I'd check your SE’s pulses BTW.
