If I use the set marker function, will those markers be visible to other users of the app? How do I make them visible?

The markers don’t automatically appear in every copy of the app.

You would need to create a refresh function that loops through all possible lat/long pairs in a cloud-based data source and creates new markers.

And you would have to decide how and how often to trigger that refresh.
