开始导航时如何防止Mapbox跳过航路点？

Question

以下是我使用Mapbox进行逐步导航的代码。

let origin = Waypoint(coordinate: currentLocation.coordinate, name: "Your Location")

let pickUpLocation = Waypoint(coordinate: pickUpCoordinate, name: "Pickup Location")

let deliveryLocation = Waypoint(coordinate: dropOffCoordinate, name: "Dropoff Location")

let options = NavigationRouteOptions(coordinates: [origin, pickUpLocation, deliveryLocation])

Directions.shared.calculate(options) { (waypoints, routes, error) in

    guard let route = routes?.first, error == nil else {
        print(error!.localizedDescription)
        return
    }

    let navigationController = NavigationViewController(for: route, navigationService: navigationService)

    self.present(navigationController, animated: true, completion: nil)
}

我放置的航路点的顺序是原点（即用户的当前位置），然后是pickUpLocation和deliveryLocation。因此，我希望第一条路线是从用户的位置到PickUpLocation。但是，有时候，如果我在pickUpLocation附近，并且开始导航，Mapbox会显示从用户位置到deliveryLocation的路线，而跳过pickUpLocation。

如何解决此问题？
