I’ve just upgraded to the latest version of the Sonos app, v80.05.04, but now I can play any content services!
I have 3 services connected including Deezer and BBC sounds, and I can search and select music or radio channels but whenever I actually try to select and play something from Deezer I get an error “something went wrong try again” but it never works.

if I select a BBC Sounds channel the play button spins for a while but then stops and nothing happens!

if I go to my music library and select tracks they will play, but if I do a system wide search and then pick something from my music library I get an error message with a link to check service status even  though it’s my local library and connects fine if I manually pick a track!
 

another pile of s**t from Sonos!
I used to be a major fan but after recent updates I’m getting close to giving up on a 8 speaker multoroom setup!
