Hello All, new to the Sonos community here. I am wanting to play music in my “upstairs group” which consists of two echo dots and a recently added Sonos Arc however, I am unable to do so. I did see, a few years ago, where this feature was unavailable (it was either one or the other -SONOS group OR ALEXA devices Group but not both) and was wondering if anything has changed? Thank you III advance. 
Mark
