I can't access the Esri World Geocoder service through ArcGIS Pro. I am signed in with my ArcGIS Online organizational account, but the World Geocoder Service doesn't show up under Locators in the Catalog pane and is not available when I try the Locate button in the Map tab. All of the tutorials and documentation I can find seems to indicate it should just be there, but it does not appear to be available. I am going through a tutorial on geocoding, and I can build and use a local locator, but can't see or use the service. What am I doing wrong?
