I have an embedded Survey123 Widget in my Experience Builder application that does not connect when NOT logged into an ArcGIS Online account. When logged out, clicking the survey widget displays a white pop-up window with the text "www.arcgis.com refused to connect."
The widget works exactly as intended when logged into my organization's user account; however, I need the widget to be available to the public.
The survey in Survey123 is set that Everyone (public) can submit to the survey. And submitters can 'add and update records.'
