I have a completely on-premise portal linked to my ArcGIS Pro. When it comes to sharing feature layers to Portal it fails. When looking in to it, it looks like that despite being logged in to my portal (admin) in Pro, it is not set as the active portal. When I right-click on it in the Project tab, the 'make active portal' option is greyed out.
I'm assuming this is the problem with sharing with portal? Any ideas why I cannot make it active in Pro?
