Version: 3.0.2
I think I found a bug in ArcGIS PRO for feature layers added via "Add Data From Path" menu.
Repro steps:
1- Add an ArcGIS Token secured feature layer via the "Add Data From Path" menu.

2- Layer added successfully after entering correct credentials but geometries are not drawn on the map while the attribute table works.
3- Check network calls, you will see the token is not passed for some requests that are needed to pull geometries from ArcGIS Server.
