I am trying to Read, and eventually Write, to an ArcGIS Portal hosted feature layer using ArcGIS Pro/Data Interoperability FME(R) 2020.0.1.0 (20200407 - Build 20218 - WIN64.
I believe I was successful adding a new service using the ESRI ArcGIS Portal (Template) (see image 1). I tested, which connected to the Portal.
When I try to add a Web Connection, I select the service I just created, Authenticate (successfully) (see image 2), but after that, I close the authenticate window and nothing is added to my available web connections, even after restarting FME (see image 3)
I'm not sure if I missed a step, but I can't figure out what's going on/not working.
