Pop-ups Not Displaying Content/Description

[upayatech]

While the app is generally working as expected, tapping on the features in first-person view is not opening up pop-ups. Only the feature's title is appearing. Tapping twice on a feature takes me to the map, rather than displaying the content of the "description" field on my Samsung Galaxy 20.

I did ensure that I selected both "title" and "description" when creating the view in ArcGIS. I noticed that using both the terms "content" and "description" were valid ways to develop my geojson file, but neither allowed for the display of that information. Here is some sample code from my json file:

{"type":"Feature","id":2,"geometry":
    {"type":"Point","coordinates":[-86.458255,43.972481,152.5]},"properties":
          {"prop0":"value0",
          "Title":"Burr Caswell",
          "Description":"1841 - 1893. Burr Caswell and his family arrived at blah, blah, blah.","ObjectId":2
          }
}

Any thoughts about how to get the content of the "description" field to display on tap in first-person view?
