Sonos' responses to common GA commands is erratic. Sometimes responds, sometimes not, with some error message. Some examples:
Me: "Play XYZ" or "Play playlist XYZ."
Sonos: "Sure, (or OK,) playing XYZ on Google Play Music. Sorry, I can't find the content you requested."
Sonos: "Sure, playing XYZ on Google Play Music. Something went wrong. Try on one of your other devices. or, I can't do that here, but you can ask me to play that on one of your other devices."
At other times, using the same command, at the same distance and volume, Sonos responds correctly.
I have a total of seven Google Home devices around my home, which all work fine.
