Nope, all working here, maybe try setting up the service using another controller device, if you have one to hand and just ensure it meets these system requirements:

Also try a reboot of the network and Sonos devices.

If using an Apple controller, you could also perhaps try logging out/in of ‘Media & Purchases’ in the iOS device settings.

Ок, thanks, I think I need to reauthorise
