When trying to view a layer on a map on a dynamic report, the participants map or otherwise, you may find that the layer is not seen even when added to the map. There are a few possible reasons for this.
Bear in mind that we are limited by Google Maps. The following is not supported:
Map layers larger than 10MB limit.
Map layers as image files (png, jpg, jpeg, etc)
If you are having issues with .KML/.KMZ files (borders, boundaries, pinpoints, etc.) or equity map layers displaying, first, try giving the page a refresh.
Another possibility is that the equity mapping layers are too large (contain too much data). If that is the case, try to to check/uncheck different layer combinations.
