When working in my Web Map in ArcGIS Online, I am receiving an on-screen dialogue following each time I save:
"These layers in the web map may not be visible to others because they are not shared in the same way as the web map. Click Update Sharing to adjust the settings of the items you can update so they can be viewed in the web map."
When I select the Update Sharing box, nothing changes. When I save the map again, the dialogue reappears.
I've verified the the sharing properties of the layers with the issue ARE shared in the same way as the web map.
I cannot isolate the issue. Assistance appreciated.
