I have Zh Google installed and it shows a basic map from the latitude and longitude I have entered. I would like it to show the KML Layer from the kml file I downloaded from the map I have at Google My Maps
I have the full url of the file loaded in the KML Layer field and I have tested that I can access that file directly but the layer does not show.
Check browser console for errors.
Probably, your template set for img or svg tags max-width:100% and it overrides my settings.
Try to add the second CSS override to map div into your template css file (at the end of file)
I don't know why. I download your KML file, and try to show - no layer.
Open it in Google Earth and save to kmz - and I can see.
Probably your file format is not process correctly by google maps API. Try to check (save it again in kml or kmz)
