There is currently an issue with route planning, where if you are trying to plan a route the app automatically assumes that the trip is for "today." However if the time to travel the route will take you past midnight, then the app essentially gets stuck in a loop of trying to recalculate the arrival time, without letting you change the day for the planned arrival. This should be rectified so that you don't need to wait until after midnight to plan a route. This is problematic especially for longer routes.
