Problems encountered so far:
1) Would not recognise my Living Room and play music then randomly did.
2) Says it cannot work in my kitchen even though works fine in Sonos App, and also listed in Alexa App.
3) When I say 'Play (artists) in Living room" it just plays the last song listed on the Songs App. No way at all to select artists via voice command.
4) When asking it to stop etc, have to shout at it.
I know its beta but this is unusable and not like a usual Sonos Beta- very poor quality needs pulling and sorting out first. Fault may be with Alexa which I have generally found next to useless, for example very poor at controlling my Nest Thermostat etc.
Fortunately the Sonos app itself still works fine and never lets me down.
Could it be because we are operating on a Sonos bridge?
