I created a custom basemap for my organization using the vector tile style editor a few months ago and was able to share it publicly without any issues. I recently saved a copy of it and changed a lot of the colors. When I try to share this new basemap I get an alert that Authentication is Required and that the "item may not be accessible to others because it contains location services that require authentication."
This makes no sense to me. Why would a custom basemap be using location services? How can I turn location services off in a custom basemap so that people without an ArcGIS account can see it?
