I am attempting to add a few more feature layers to our open data portal. I have followed the same procedure as I have done before, except now, the feature layers are under "Items" in the ODP Data Manager page rather than under "Datasets" where things seem to work. These "Items" do not show up in our ODP. What is the difference between "Datasets" and "Items" and why do Items not show up in the ODP? How can I get them to show up.
My process is as follows:
Add new layer to MXD.
Overwrite Feature Service / publish to our ArcGIS Server.
Create Feature layer in AGO that points to the REST endpoint of the new layer.
Share new layer with ODP enabled group and Everyone.
