I have a straightforward relate that I set up in ArcGIS Desktop that connects properties (1) with sample results (0 to N) per property.
In the map viewer, I can select the properties, and when I do, I see ALL records from the relate table. When I select "View Related Records" from the popups, the records disappear. I do see field headings, and I also see a label that says how many related records are selected, none of which I can see. The records just go blank.
Do relates have to be published as feature services to work in Portal? I hope not, because that would destroy the organization of the map service, but that's all I'm left with at this point.
Thank you for any assistance you may be able to provide.
