Feature templates configured in Map Viewer Classic do not update in the ArcGIS Field Maps web app templates when the field value is changed and the Types (Unique symbols) style is used.

Solução Provisória

• In Map Viewer Classic, click Edit and click the Manage button at the bottom of the configuration window. Then, click Save Changes to save the edits. The edits display correctly in the Field Maps Templates.
• Additionally, the issue does not occur if the symbology of the same field is edited. Save the web map and go back to the ArcGIS Field Maps web app.
