There must surely be a way to change the URL to a ArcGIS Online Content item that is a Document Link. If you go to My Content, I have several items that are of Type-- Document Link. We changed the virtual location of some of these and I can not find a way to change the URL. My only solution is to remove the item and add back with the new URL which includes redoing the summary, tags and the icon. When I go to edit the content item, I see the ArcGIS Web API Rest Connection URL but I don't see anyway to change it.
Please let me know if you do know how to change it?
