In the ArcGIS Survey123 field app, a survey form does not load if the URL from the ArcGIS Survey123 website used to open the form directly in the Survey123 field app, is used by embedding the URL from the Configure pop-up section and accessing it in the field maps.
This issue is not reproducible with the June 2022 release of ArcGIS Online. If the issue persists, contact Esri Technical Support for continued investigation.
