Comments do not display in the Crowdsource Reporter application

Description

Crowdsource Reporter is an application template for ArcGIS for Local Government, and is also available as a configurable template in ArcGIS Online. The application template allows managers to collect user input, such as reports, comments, and votes, from a variety of mobile devices as well as desktop computers.

In some instances, comments do not display in the Crowdsource Reporter application but are viewable in the attribute table.

Cause

This issue occurs when the relationship class between the feature class and the comment table is not configured properly or is missing altogether.

Solution or Workaround

Note: 
An ArcGIS for Desktop Standard or Advanced license is required to create a relationship class.

1. In ArcMap, create a table with a comment field set to String data type, and connect to the desired feature class based on a common unique identifier, such as Global IDs (GUIDs).
2. Add the table and its associated feature class to the map.
3. Publish the map to ArcGIS Online.
