I'm seeing some strange behavior in ArcGIS Online Assistant when using the tool, "Update the URLs of Registered Apps and Services" in Portal. When selecting the URL of an item and then clicking either the Reset or Update button, AGO Assistant crashes out to the login page. If I clicked the Update button, I do later find that the update was actually done. Similarly, though not catastrophically, performing the same action when in ArcGIS Online rather than Portal, I see the login page flash briefly before returning to the page in AGO Assistant. This happens in IE, Chrome, and Firefox.
Does anyone have any idea what's going on and how I might fix it?
Thanks,
Marc
