When creating a survey in the ArcGIS Survey123 website and adding a shared update group to edit the survey responses, members of the shared update group cannot edit the submissions added by other users if the survey is shared publicly.

Workaround

When a survey is shared with everyone, the members of the shared update group can edit the survey submissions directly in the attribute table. Another option is for the survey's owner to edit the fieldworker view layer’s settings and add an update, 'editors can see all features' and 'editors can edit all features'. When a survey is shared publicly, the fieldworker view is also shared publicly, which means adding these settings allows members inside and outside of a shared update group to edit.
