I need to be able to fix a link between a WebMap and one of its layers. The layer was moved to a new URL. For comparison, in ArcMap, the Table of Contents for a layer with a broken link would simply have a red exclamation point and I could repair the link. But in a WebMap, the layer with the broken link is entirely absent from the Table of Contents, so I can't fix the link. If I just load the layer as a new layer from its new location, I will lose all the heavy pop-up customization that the existing WebMap layer has. Any way to repair a layer link in a WebMap? Thanks!
