Have you set up a BBC Sounds account?

Thanks for the reply. Sonos took me to the BBC website to login using my existing BBC login, which I did, and then returned to Sonos.

And all is well?

Sorry for the ambiguity: no, nothing happens. I get a blank screen and ‘Unable to browse music’ with a grey folder icon. Both on my iPhone and Desktop Sonos app,

 Is there a minimum version of Sonos this requires to work?

I seems S1 gives more problems than S2. What version are you on?

… 8.4

But I have lots of other music services on there with no problem. Perhaps this is a step too far for my system, if nobody else is reporting difficulties setting it up, it’s probably the old system.

I don’t think so.  Have you checked that your Sonos account is set up with location of UK?

Edit - sorry, just noted the 8.4 software is what you are referring to.  Yes it’s probably that.

What is keeping you on 8.4?  CR100?

Yes, exactly: the CR100 mounted on the kitchen wall still works perfectly!
