Is sign out everywhere working?

[Simcevoy]

Is the sign out everywhere feature working? I've tried to use it but after clicking the button I'm still signed into the website and iPhone app. It doesn't seem to have signed me out anywhere!
Urgently need to do this as I've left a cottage with a sonos system signed in to my spotify account.
Thanks.

You can also try changing your password. That will also log out everywhere.

Hi even when you sign out everywhere and change your password a Sonos device will still be able to sign in as you
