I just created a distributed collaboration between Enterprise Portal (11.1) and our ArcGIS Online organization and have had success sharing items from our Portal to ArcGIS Online.
But, with our hosted feature layers from spatiotemporal big data store, the collaboration does not work. Instead of having a seamless sharing experience, ArcGIS Online prompts for authentication for spatiotemporal big data store hosted feature layers.
I am hoping for a "simple" way around this, for a seamless sharing experience (no authentication needed) with ArcGIS Online members that includes spatiotemporal big data store hosted feature layers.
