Soptify can't forget Sonos speakers?

[oortone]

Hello!

I have Spotify Family subscription and when connecting my own account to Sonos that gave access to Sonos speakers for my children too. I don't want that.

Seems there's no way in Sonos to turn this off. So I tought I might go into my childrens Spotify and "forget" the Sonos Speakers. Sure enough, there's the forget option ("glom hogtalare" in my Swedish version) but the speakers are not removed anyway.

Why?

How can I remove them?
