I’ve been using spotify on Sonos for a couple of years and it has been fine. Up until recently. Now, if I ssearch an album and select “play whole album now” it plays one track and then selects its own random tracks thereafter – nothing I’ve ever heard, liked, added to a playlist or anything. Any one else had the same or know what’s happening?

Are you still logged in? And paying premium?
Sounds like it’s operating on the ‘free’ version where it just plays random stuff.

Logged in and premium. Think it’s just over Sonos so maybe it’s not recognised there.
