The item for the layer (http://www.arcgis.com/home/item.html?id=433f02a522ad4c57ac812aa2abbe1ad2 ) is updated with the correct URL, but the webmap (http://www.arcgis.com/home/item.html?id=8c26803af6474f4782c2712b475b1fbf ) is still pointing to the internal server name. Can you re-add the layer to your webmap, save and try again?
Hi Brian, Error 400 means export fails. Are you able to export any other web maps or layers from ArcGIS Online or Maps for Creative Cloud Organization? If possible, can you share the url of the layer you are trying to export so we can investigate the problem?
I've tried layers and it's hit and miss. If I zoom in close I have a good chance of getting the feature imported, but I need ALL of the Council Districts for Tulsa in my import. Here is a video of another attempt but I'm using a WebMap this time.
