I'm getting up and running, super exciting! :-)
An issue I run into is related to the Developer Functions in the Reality Editor. According to http://www.openhybrid.org/adding-web-content.html, turning on Developer Functions should allow me to move/resize the interface. However, nothing happens when I drag the interface. When holding my finger down, it seems that the iOS interface "takes over", and a text-like selection is applied over the image.
Is this a known issue? I'm on iPhone5s, iOS 9.2.
