I'm working with Delphi XE6 and your latest 1.8.0.3 version of the TTMSFMXWebGMaps.
Sometimes when I add the first TMarker it's duplicated over the WebGMap, I use the Markers.Clear method in order to remove all the Markers on the Map but it doesn't refresh it.
How can I force to repaint the Map?
Right now the only way to refresh it was to use zoom. But this is a bad idea.
