There was a problem hiding this comment. I suppose it's in the scope actually. I had the same doubts, found that RouteLegProgress and RouteStepProgress are not null, so we should be good. |

what is the difference between unexpected and expected closure? Is the unexpected the one we receive after route refresh?

the difference is in snapping options (see com.mapbox.api.directions.v5.models.RouteOptions).
Whenever snapping is not allowed, that means the closure is unexpected
