When there are two or more map pins that overlap, you will see an icon with a plus sign in the middle.
As you zoom in, the map pins will change back to normal if they no longer overlap. However, if you have zoomed all the way in and the pins still show a plus sign, that mean the map pins are in the same exact location.
Select the collapsed map pin to view or take action on all the pins in that location, Please note the line connecting them will meet where they are actually located.
If you are on the Routes page and have expanded a collapsed pin, select each stop to add it to that route. It is important to remember that after a stop is selected, the pins will collapse back down into one. To add all of those stops, expand the pin and select the others until all stops are selected.
