Having a issue with the ControlApp app on my iPhone. It was working fine but now all of a sudden it's displaying a progress wheel on the screen. The app shows the status of the volume even when I raise or lower it on the receiver(VSX-42), but won't let me controll anything. Just keeps giving me a status wheel. I reset my modem and checked all connections, blah, blah, blah, and all the other usual suspects. Anyone else have this problem?
