Why won't the Attribute Expression configured for a Pop-Up save and display to a layer shared across Web Maps?
The following Arcade expression was a great work around for displaying the acres of a selected feature with the default Web Mercator Projection.
When the expression is added to the Pop-Up of a layer of a Hosted Feature Service shared with my work group it only works for one session in Map Viewer. When the Web Map is opened latter the expression output won't display. The expression still shows in the Pop-Up configuration menu, but it doesn't display an actual output in the Pop-Up.
The Feature Service and Web Maps in discussion are shared to a group and cached to Collector.
Any ideas on why the saved Arcade expression quits displaying?
