On Spotify, I can have a 'Crossfade' of up to 12 seconds. I hear the music blend in together with this while listening through the Spotify app. However this does not seem to carry over when listening to the same music off of my Spotify app through my Sonos players. Is there something I am doing wrong? I searched through the Sonos configuration and menu and do not see any way to do this. It is in the Spotify app though. Any thoughts?
