Has someone else used your Roam?

To register the Roam back to your own Sonos account, in the Sonos app, go to Settings > System > Transfer System Ownership and follow the prompts.

Thanks. My husband uses the app via his phone, but he’s signed in with my details. I’ve just done what you suggested - Settings > System > Transfer System Ownership, and I get -

“Transfer Sonos, This will register your Sonos system to a different account - Continue”, but the next panel is the Sign in to Sonos page with the unknown email address. I do however have another option which says ‘I can’t access this account’, so when I select that, it then prompts me to do things I’ve already done, such as change my password and reset the app, but it all just brings me to the sign-in page with the unknown email address.

When you select “I can’t access this account” it should prompt you to input your Sonos account credentials of email/password.
