About two days ago (Aug 8th 2019), Spotify no longer connects to my Sonos speakers. This has been working up until then.
Logged in to Spotify, I see my Sonos speakers, try to connect and nothing happens. Using Apple phone, Windows 10 Surface. Neither work.
Removed the Spotify service on Sonos and re-added. Restarted both devices, reset the Sonos speakers (unplugged, replugged). Nothing seems to work.
iPhone 6 and Surface Pro WIndows 10.
iOS 12.4, Windows 10

That unfortunately did not solve it for me.
However allowing mobile data did resolve it on my iPhone. See:
For family members with an Android phone the problem persists.
