This pop up is a layer of awareness we provided on the latest release to advise users of an issue with loading a given map.  We have had some users experience app crashes, which was caused by their map.  This alert provides a warning in order to prevent a crash.  We are monitoring this situation across our customer base and are working to prevent this pop up from reoccurring.  Often times all the user needs to do is tap the reload button and the map should render appropriately.
