I'm trying to add data to my maps that another group maintains in Google Maps. I can add the data as a static KML without issue, but when I try to add it as a Network Link KML (adding the KML or KMZ file to the map), it shows up as a layer with the expected name but none of the data is present. Network link is preferred because the data is regularly updated.
