My App is displaying a map with Annotations and Overlays and it's working pretty well.
Nevertheless, when my App is moving to background because the user has moved to another App and then come back later to my App it happens (not systematically) the map tiles are missing. The user needs to pinch the map to zoom in or out to display the tiles again.
Do I need to do something when my App is entering in foreground to make sure the tiles are up to date and displayed?
Thanks for the help,
Sebastien
