The webApp Builder for ARCGIS is a wonderful tool, it allows one to quickly create standard sites with various layouts, themes, wizards, and headings however after following the deployment instructions to add the site to a webserver the users are asked to sign in to a ArcGIS portal even though the site is publicly shared. Why does a WAB generated map viewer web site prompting for a Portal login? Has anyone else experienced this issue if so can you please let me know how to deploy a WAB site on a web server without ArcGIS Portal or ArcGIS Online getting in the middle of the transaction.
