The app isn't working right for me currently.
Here's my thread on it. I started you at the page where I started correspondence with Audyssey, then Marantz. The last page or two I pasted a couple of emails I got from Marantz about the issues I'm having with it. The way they word it, not everyone is affected, but they're working on an update so enough people apparently are.
That being said, I do know as much or more than anything I could find online about it. Hit me up any time.
