I am having trouble increasing the size of the Placemark (font size, and icon size), and also using an alternative pushpin to mark the location. Below is a KML file I put together from looking at other examples. However, it does not work. It still only displays Baltimore, with the default yellow push pin, in the default font size - when I upload the file to Google Earth Studio as an overlay. Does anyone have any ideas what is wrong?
