I'm taking my first stab at the web app builder and I'm pretty impressed. An issue arouse, however, when I tested the app on a tablet and was unable to load the app. It wasn't a signal issue, I was able to run the pretty much same JS app in the same area. It seems it only works on wifi. I take it I am missing something here?
Also, the only layers that seemed to load were tables that were unable to open and a composite locator service that worked fine(and was the only layer I was actually prompted for a password.)
