If you want to create an copy of an existing map, please navigate to “list all maps” and search for the map you want to duplicate:
Tick the checkbox for this map and then in the bulk actions control panel below the map list either select if you want to duplicate the map only or if you want to duplicate and assign the same markers from the original map. If you chosse the second option, the markers itself will not be duplicated, the will just be assigned also to the duplicated map.
Finish by clicking the “Submit” button.
