I had a question regarding Spotify connect. The information I read about the feature is that in order for it to turn on, the devices have to be on the same network. However, I gave my account info to a good friend who is overseas, stationed in Japan. When he logged in he was able to change my playback with his phone. How is this possible if we are not on the same network? Is there a way to turn this feature off to avoid confusion in the future? Any help will be greatful! Thanks!
