I didn't need a mapping capability in my video portfolio app, but I thought I'd try to add this feature anyway. Unfortunately, even after following the instructions to the letter, I couldn't get a map to display in the HTML5 preview. I also tried it on iOS and Android, but no luck. Too bad, because I really wanted to try the "augmented reality" map view.
