On this site: https://valeyard.org
I have a map, with a custom marker image, which works fine when inside Pro: https://share.cleanshot.com/0FVKCqtg
Looking at the site as a regular user, the marker just won’t show up, if I wait a while sometimes it shows up. It’s there in the page source for the map.
Can you check this out? This is Pro 6.5.1.
Thanks, Bill.
