My Question or Issue

Spotify Connect does not recognize Sonos devices. I am able to play Spotify from within the Sonos app, but not from Spotify. I can use Pandora and Audible from within their apps onto my Sonos.

Talked with both Spotify and Sonos customer service, as expected got bounced back and forth. Sonos customer service mentioned that even though Spotify was registered within the Sonos app, from the diagnostic report, it shows that Spotify is not registered. Is there some issue from Spotify here where the registration is incorrect?

When I restart the Sonos speakers (or reset my Wifi)  the speakers show up briefly and then within the hour, are unavailable in Spotify Connect. On the flip side, I am continually able to see my Google Home and Chromecast devices on Spotify Connect.

To provide details on my wireless setup, both the 2.4 and 5GHz bands are on the same SSID, all devices connected as expected on non-overlapping channels - from my router information.

I've tried all the advice listed on this (and Sonos) forum, but unsure where to go from here - any help/advice would be appreciated!
