Hi,
We have in the past passed itemids to the explorer.arcgis.app to get explorer to open a web map.
That doesn't appear to work with fieldmaps.arcgis.app.
https://fieldmaps.arcgis.app/?itemID=225b4939fad9432296c949ebb104651f&portalURL=https://fakename/arcgis
I know if I add the user to a group and add the map to the group it will be visible, but our users are being automatically created in Enterprise when they use their enterprise logins.
We're using ArcGIS Enterprise 10.7.1.
Thanks,
Peter
