Just downloaded the latest version (2.4.2.16291) from the tinterweb but whilst planning my trip to France this weekend I get an error message in the 'Flight Details' tab saying "The journey requires more fuel than the selected aircraft can carry". I try to add fuel, but there does not seem to be the "Planned" slider facility in the fuel section to do so.
I have SD on my laptop and Ipad and have not upgraded but have the "Planned" in the flight details tab and can add fuel.
