I solved a route for field work in ArcGIS Pro, then shared that layer to our Portal to be used in Navigator. The route shows up in the Routes tab of Navigator, but I can also go to the layer in our Portal and click the "Navigator Stop List" to bring into Navigator. The thing is, the routes are different from each other. Why is that? When I load the stop list from Portal, what road network is being used for the route? And what about when I hit "Optimize Route" in Navigator? What network is being used? Our road network isn't on our Portal, so I'm just curious how the optimization is being done on the fly.
