Problem: I have set my map initial zoom level to center and zoom in to show all the markers, but when I display the map the initial zoom level is zoomed out showing the entire global map.

Solution: In this case the map is not displayed when the page is loaded, so the initial zoom level calculations are inaccurate. You must trigger a map reload function when the map is displayed to calculate the initial zoom level correctly. The correct function to call is:

WPViews.view_addon_maps.reload_map("map-id");

Place that code after the code used to turn on the map display, and replace map-id with the ID of your map.
