Problem:
Can Latitude/ Longitude be used dynamically for maps
Solution:
Is this data coming from a specific CPT, you can try these steps:

1. Use a known address at first, and save it for your post. For example, "Paris France".
2. Edit the post, and scroll down to the address field. Click Show Coordinates, and update these fields with your desired coordinates. You may have to delete the content before pasting your own in, it's a bit tricky but it should work. Click the map to refresh it and confirm your coordinates, then save.
3. Now your address field will display as the Lat and Lng coordinates, and the map marker will use these new coordinates.
4. If you need to use the written address in a View, you'll need to include that as a separate custom field, or as the title of the post, etc. If it's a separate custom field, then you can use conditional logic easily to determine when to show the address field, and when to show the lat/long override field.

If you still have issues after this procedure, please open a ticket so we can analyze it.
