I am still looking into the issue. I find the plugin is correctly getting the coordinates and saves it, but then something is deleting the coordinates and I am not sure what that is.
I find in our beta of 3.10 that the issue is resolved. I can provide that to you, it is stable, but only a beta so it may have unknown issues.
Also, I do find that every business on Tulip Street does not have the correct coordinates returned by Google so that may have to be manually added.
And finally, please note we make take up to 24 hours to respond to each reply to thread you create per our terms and conditions.
Let me know if you would like to test out the beta to resolve this.
Thanks
