Been using Sonos radio “Rock Road Trip” for a couple years now. Today I got a login notification. I logged in and still got this message… “Unable to play ‘Sonos Radio’ - access is denied”.
I am able to play other music I have on my phone… frustrating.
Try re-authorising Sonos Radio in the app.
Go to Settings > Services & Voice > Sonos Radio > reauthorize account
That worked! Kind of buried...LOL
