I just got new Sonos One devices and trying to add my first one to a “Downstairs” group that contains an Amazon Echo Dot (oder model) and an Echo Plus (also, not newest model). The Sonos One shows as incompatible. When I remove the echo devices from the group and add the Sonos One, then the echo devices show as incompatible.
I did add the Sonos skill and followed all those steps. I also disabled and then re-enabled the skill several times. I made the Sonos one a preferred speaker for the “Downstairs group” but it just accepts the command but does not play on it when the other (echo) downstairs speakers are playing.
Any help will be very much appreciated!
