———————————————————————————
I have tried to plan several routes from UK addresses to French addresses, the App selects what it perceives to be the quickest route despite me having a planned ferry crossing. I have tried to add the ferry terminals in as waypoints but the App takes you to the terminal then routes on to a different departure port. See photos. This bug makes it impossible to workout the best charging strategy for the entire trip. Would it be possible to allow the user to select a sea crossing route Ferry/Eurotunnel in either the settings or like a predefined waypoint (with a different start and end point but zero distance) so the entire route can be calculated as a whole rather than in parts.
