Trying to add the Story Map Crowdsource beta to an instance of ArcGIS Portal without success. One entry in an FAQ states that the Crowdsource beta is not supported in Portal. Is that the case? We have a production instance of Portal 10.4.1 and a sandbox instance of 10.5.1 running on an intranet. We downloaded the Crowdsource zip file and added it to the 10.4.1 instance. The 10.5.1 instance has the template included. In both environments, the Crowdsource builder tried to redirect to an external page (links.esri.com/storymaps/crowdsource-app).
