That's great.  They had said it was working again a couple of weeks ago when clearly it wasn't. 

Hi folks. Thanks for reaching out and welcome to the new users here in the community. We have coordinated this with Mixcloud and they are currently working on their infrastructure. You may experience service interruption during this period. @Airgetlam is correct. You can always check the progress on https://status.sonos.com. Please feel free to reach out in the future if you have any other questions. You're always welcome here.

Hopefully this gets sorted soon as it’s a real problem that’s driving me up the wall.
