Always hangs

For all I know this is a great app. But I cant get to that greatness because it always hangs on launch.
The hang appears to be in an attempt to contact the ad server, since the entire front screen UI draws, except for the ad at the bottom which remains blank.

I will just note that, even assuming they fix their ad server, this suggests an organization that does not know how to write decent iOS apps. Apple have been telling developers for years to put network operations on separate threads, not the main UI thread, both to improve performance and to prevent precisely what we see here --- the app hanging when there is a network problem.

There are other mall map apps which work substantially better. Id recommend Mall Maps Mobile which launches fast, DOESNT HANG, and, while the UI is far from perfect, its adequate.
