Buggy, no on/off switch - SAVE YOUR $$

This app promises a lot more than it can deliver. I have had synch issues and basic functionality like on and off is not supported. It does support a lot of different features of the unit but the sync issues and lack of basic commands makes this a waste. I have to revert to the free Marantz app
