I need map to be centered on marker every time i go on my webpage. Right now is centered on deparrture aiport. So this is map for flights, as flight is ongoing , aircraft (marker) on route, map should be tracking it so every time i refresh my wepage, map should point to marker, not to departure airport. Can anyone halp me. Thank you
