When I connect an AirPort Express to my network (AirPort Extreme) and run the iOS App I have no way to see the Express. When I run the OS X App it looks the same except it has a click bar in the top left that says "Other AirPort Stations". When I connect the AirPort Express it shows a little 1 in it and I can click on the bar and setup up the Express. However this selection bar is missing on my iOS (iPad) App and I see no way to setup a new AirPort. How do I get this selection onto my iOS App?
