Loving the capabilities of the Portfolio App for newbs like myself. I've got 8 maps/tabs in there, all set to public-level sharing. The Portfolio is set to public-level sharing. But now 3 of my maps/tabs are suddenly asking people to sign into their ArcGIS account in order to access them. The 5 others open just fine... how do I get all the tabs working and accessible to those without ArcOnline accounts again?
