I have been anxiously awaiting this App update for this very reason. In addition, the App lets you alter the starting SOC of the vehicle (important part of planning for instance if you expect to charge to 100% prior to departure).
Indeed, the new App (4.27.5) does indeed support this which is excellent, BUT
I was very disappointed to find that the "send to vehicle" function does NOT include the waypoints and dumbly only the final destination is sent (completely ignoring any of your desired waypoints). This is a disconnect with a half-assed function that is not integrated between the App and the Vehicle. What is the point of being able to map out a route with the desired waypoints on the App, but you can't send it to the vehicle ???
Can anyone else confirm or deny my findings? I am running 2023.44.1 on the vehicle.
