Spotify must've suffered a breach. Group sessions or Spotify Connect is basically a stalker's wet dream. It allows strangers to listen to you. The app even sends a message that "someone you know" is listening and allows you to join their session, even if that someone is a complete stranger, which was my case. This reeks of privacy invasion and there's NO way to disable this garbage. I had to reset my password. Spotify would save so much trouble by just enabling 2 factor authentication, but no.
