I have downloaded Roon Core onto my iMac and it is working fine. I am trying to install the Roon Remote on my iPhone 5S. When I select the Install button I get the message: ‘Cannot download - This app is not compatible with your device’ in spite of the fact that the iPhone 5S is on the compatible list.
I am using an iPhone 5S (Model ME486LL/A) running iOS 10.2.1. Am I missing something important (wouldn’t be the first time)?
