After having my app in review for a week, I've just got some feedback. Now the thing is, there are no "accounts" in it. The app is designed to "automatically activate" when you're at a certain location (using GPS) and make available extra functionality (functionality which doesn't really apply if you're not at the aforementioned location). I did anticipate this might pose a problem for the reviewers, which is why I clearly stated that some of the functionality is not available unless you are at a certain location. I even provided a few example coordinates, hoping they could use them to override the positions and thus test the location-based features. I'm at a loss with what to do, should I just attempt to resubmit the binary and give a much clearer explanation? I don't want to keep submitting it, only for it to be rejected every week!
