When I'm not logged into Field Maps, clicking on a URL in the format https://fieldmaps.arcgis.app/?itemID=<myitemID>&referenceContext=open&portalURL=https%3A%2F%2F<myorg... shows the message
"Unable to open
The map needs to be shared with you"
After logging in, I am able to open the field map by clicking on the link.
The URL has been generated from the Field Maps Designer > Sharing page. The Web Map is hosted on ArcGIS Online.
The portalURL documentation states that the user will be "taken directly to the sign-in screen for your organization and prompted to sign in"
Any tips on how I can get this to prompt me to sign-in rather than showing this error message?
