It works fine if we are using fields from our table but the moment we try to use an arcade expression the export button just spins. The arcade expression works in pop-ups with no issues, its just the exporting that isn't working.&nbsp;</P><P>Thanks for any help.</P> Fri, 19 Jun 2026 18:03:53 GMT LindsayJanik1 2026-06-19T18:03:53Z https://community.esri.com/t5/arcgis-instant-apps-questions/public-notifier-instant-app-breaks-with-custom/m-p/1709026#M3800 <P>We are trying to build a mailing label application using the Public Notifier instant app in Enterprise 11.5.
