When I am driving for long periods, Waze in some periods, updates the route. Unfortunately, it first finishes the old navigation information from screen. This is the problem, because if there is no internet connection available, the route is not calculated and the screen shows no navigation information.
As Sometimes I drive for 100km with no internet connection, with no orientation. It would be very useful if Waze, before finish the old information, check if internet connection is available. If not, the old navigation screen is much better than nothing.
