I have successfully “Shared” (published) my ArcGIS Pro desktop map to my ArcGIS Online subscription as a “Web Map.” I made a change to the Pro map at my desktop and want to overwrite the map and data already in AGOL. When I try to overwrite, I get an Error Message that states: A web layer named “<name>” already exists. Please choose a different name that is unique with your organization.
What is the suggested workflow to update an AGOL web map and data from my desktop (ArcGIS Pro) to AGOL? Must I log into AGOL and delete all existing map and data items in My Content every time I want to update my web map from my desktop? Am I jumping the gun with ArcGIS Pro “prerelease”? Will this be possible with December updates to Pro and AGOL?
