Will not load light pollution layer, minimizes app into background mode – Light Pollution Map - Dark Sky Review

My Astrophotography instructor from a local College recommended this app. Very disappointed, it is unusable. Allowed it to use my location while open, selected light pollution map from list, the satellite view displayed. Only 30% of the light pollution overlay manages to load from the left side of iPad Pro display, then instantly the app closes! Double click my home button, and I see the app in the App Switcher. There are no updates in the App Store.
