Pins not resizing
Primary reason I bought this was for the pin markers resizing responsively. I have changed the Responsive Settings with Fluid/Responsive, and played with the Pin scale coefficient. I have installed on a test site with just Twenty Seventeen. You can view the tool at this site, which is the one I need to use it on, https://sandpointwaterfront.com/dover-marina-test-map/ as well as this site which has no plugins activated other that your image mapper: http://rbcdev.com/.
