I think I read that you added a feature to indicate that locations are loading, as it currently looks like it isn’t working if there are a large number of locations, but if you wait they show up.
Do you have a way to indicate that the locations are loading?
The Locations oading indicator is the Import in the back end. we answered the email, if you want the front end to indicate they are loading that is customization. If you are referring to the Power Import feature let us know what is happening, it could be your server side.
