Someone connected device

someone has attached device to my account. Ive.tried.changing password, logging everyone out and delete all devices but it's still there.

Exactly same here. I see "office speaker" connecting to my account. I talked to support, they said they will fix it. They've fixed, it was working well for 3 days, now that "office speaker" is still with my account and messing up with my playback. Logging out, changing password, etc, does not helps.

So, after I'd change all the passwords, logged everything out and disconnected all devices (with the device still showing up), I restarted my phone. That seems to have done it. Device is gone. It's odd as it was 'Spotify Connected', which implies a speaker - not sure how they managed to both play music and change my playlists.
