PROBLEM
Creating symbology based on multiple fields is required to assist in pattern analysis and data visualization. More than one field can be combined through the Change Style pane based on the list of attributes in the map. However, ArcGIS Online is unable to symbolize two text fields in the map viewer.

As a workaround, follow the steps below:
