Figured it out! I will need to update each post for the map to appear. This is not a problem as the site is in the early development stages and I will need to go through and add some additional data anyway. So — thank you!
Thank you for your swift response! So with those fields filled in, I am still not seeing maps. For “Basic Settings” I have selected the custom post type “Chamber Members”, automatic display is “Bottom of Post”, Directions “Google”. Is there something I need to do to cause initial generation of the maps, or a line of code I should insert in my single post display template? I have customized these templates, so it may be that I’ve inadvertently eliminated some necessary piece of code?
