When starting navigating on a long course(500km an more) with many navigation points it takes a lot of time to start it and during some calculations the maps i frozen. Before some updates this was also an issue, but the map was not frozen, there was only no guides, but the course was visible on actual map. This was much much better then a frozen map for 10 minutes.
When during the calculation i go off course, sometimes i see course calculation error and i need to restart the navigation.
Could you please rollback the changes?
