Have roon Headless server running on a proprietary window based computer using Windows 7. Have the IOS app installed on my IPhone 6+. Have been using system for a few months with no problems. Today I start up the Roon server and go to my Iphone for the remote control. All I can get is a white screen with the Roon symbol and the lines coming out of the symbol are moving. Can’t get to any menus. I let it run for an hour and no change.
Appreciate help
