I have the TX-NR709 and use the Android app to listen to Spotify on it. It works awesome and I really love it. The one issue I can't seem to resolve is that the music I listen to on my home theater doesn't connect to my Spotify account. I know that it is set up correctly because I can listen to music, but when I look at my Top Tracks listened to, none of the music shows up. Also, none of the music I listen to is published to my Facebook Timeline.
This isn't the biggest issue, but I really enjoy Spotify and don't understand why these functions aren't available. Does anybody know why this would be?
