I'm not sure this is the right section but my problem is not OS-related, so I post it here.
Since the update what brought us device selection Spotify does not work well. For example my phone (BlackBerry Q10) somehow found a device called "Josh's iPhone" and started to play songs from his account. Just a couple minutes ago I was listening a song from one of my playlists and suddenly the track stopped and Spotify started to play some german audiobook. Even on desktop the app plays on this iPhone. Why?
And of course all of this Josh character's favourited songs, artist, etc are in my "my music" library. Why? I do not want any other music in my library than those I favourited.
