Hi @JohanRHolm, welcome to the Sonos Community!
I’m sorry to hear you’re having issues with Sveriges Radio on your Sonos system.
I’ve had a look around and can’t see anything on our end about a specific issue with this service. What I’d recommend would be to reauthorize this service in the Sonos app by heading to Account → Content Services → Sveriges Radio → Primary Account → Reauthorize Account. If you can’t reauthorize, you can instead remove the service then re-add it to do the same, by heading to Account → Content Services → Sveriges Radio → Remove Service.
If this doesn’t resolve the issue, I would recommend submitting a diagnostics within ten minutes of the issue occurring, then reaching out to our support team for further troubleshooting assistance.
I hope this helps!
