Hello @Humlebæk, welcome to the Sonos Community!
I am sorry to hear you are having trouble authorizing Sonos Radio via the Sonos App.
As a workaround, could you try this via the Sonos Desktop Controller?
We are investigating the issue, but I do not have an ETA to share for the fix. I will reply here when I get an update for this.
I hope this helps.
