Here's the situation: Deployed Parcel Drafter to our Portal using Hosted option. Got it working. Now I need to be able to see the Parcel Drafter service in ArcMap to use it as a backdrop for bringing those parcels in. We map our parcels on Amazon workspaces with a log-in that is not our enterprise log-in, it's one we made via Amazon. We were lagging behind in Desktop versions, so I upgraded to 10.6.1, which allowed me to add a Portal to the ArcGIS administrator.
Because we normally use enterprise log-ins to access our Portal, we made a "Public" log-in with it's own password for situations such as these, I can sign in as that to Portal in ArcMap and I can see things that are shared appropriately.
All of the above information may be moot, but I wanted to include it just in case. The issue is, when I try to add the service to ArcMap, nothing happens, it doesn't add it, no error message. I can see it everywhere else just fine, ArcPro, Portal, ArcOnline...but Desktop can't seem to handle it. Do I need to backtrack and store this data in SDE in a more traditional way for ArcMap to be able to see it? Am I missing something really simple here? I can add other feature services that are older and published from our SDE database, but not this one.
