In ArcGIS Field Maps 25.2.x, the last edit summary does not display even though it is included in the pop-up configuration of the web map.

Workaround

1. Use an attribute expression in the pop-up with the following:

// Retrieve the editor and last edit date

var editor = $feature.Editor;

var editDate = $feature.EditDate;

// Format the date nicely

var formattedDate = Text(Date(editDate), "MMMM D, Y h:mm a");

// Return a combined string

return "Last edited by " + editor + " on " + formattedDate;

2. Add the expression to a text field and place it at the top of the pop-up.
