Added waypoints along listed gravel / forest service roads and am seeing the blue route line significantly disconnected from the waypoint and destination
The problem is that the last routes are on small roads that which may have different conditions. If we allow driving on these roads in your plan, all similar roads are allowed without us knowing their condition. My colleague is looking at how we can resolve this in a good way.
We have had another user with this problem and are investigate the problem. I will get back to you as soon as we have solved it.
