I have tested a B&O speaker (BeoPlay A9) which is able to play spotify playlists as soon as my device is connected to it.
Now I have an issue because whenever the BeoPlay owner is using his speaker, my spotify account is switching the music to this speaker (which is not mine).
How to unlink this speaker? It appears in my Spotify Connect list, I have tried to look at my spotify profile but unless to unconnect offline device (doesn't work for my problem), I don't find any solution.
Can someone can help me?
