I am trying to figure out why one of my web maps is unable to access the related table. When I open the webmap in the old map viewer, I see the "Show Related Records" at the bottom of the popup, however, when I open the same webmap in the new map viewer this does not exist.
I do have another webmap that contains a layer with a related table and it works just fine with the new map viewer.
I would really like to avoid re-creating the table/layers/relationship...
