In the ArcGIS Field Maps app, the error message, "The form contains unsupported data" is returned when a combo box question is added to the form through the ArcGIS Field Maps Designer and if the map in question already has offline areas generated.

Additional Information
This is working as expected. When making schema changes to the underlying feature service layers, the existing map areas need to be recreated instead of updated to pick up those changes. In ArcGIS Field Maps Designer, when adding a new Basic or Choice element from the list to the form, a new field is added to the feature service on the back end. This issue in Field Maps is happening because the form references a field not present within the local offline geodatabase. Refer to the `Recreate` section at https://doc.arcgis.com/en/arcgis-online/manage-data/take-maps-offline.htm.Workaround
Perform one of the following workarounds:
- Configure the form with all the questions prior to creating the offline area.
- Delete the old offline area and create a new one.
- Remove the combo box question from the form and add the field with its list manually through the Data tab of the service. However, this requires the deletion of the old offline area and to create a new one instead.
