We're working with Spotify to resolve an outage causing issues with browsing playlists and searching within Sonos. We'll continue to update this thread when we have more information to share.
Please note, there is currently another issue we're working with Spotify on regarding being unable to use the Spotify app on Android devices to control Sonos. That is being tracked here.

Please go ahead and try out Spotify again on Sonos and let us know how it goes.
