The controller on my Mac v.16.2) was working until a few days ago and then I got "system not found". So I have slowly been going thru the steps listed. This morning I checked to make sure that the speakers were in fact "turned on". When I hit the play button, music began playing. I assume this was from the last service I played before the "system not found" alert. So if music is playing, how can the App not find the system which is in fact "there".

Also, v.80.02.04 on my iPhone is still not connecting.

Any explanation?
