get last track not showing last flight data

Flight KAL336 if i do a call from api is not giving back data, as information from the api this method should retrieve the last track made in the last 24 hours. Flight departure was on 5.56 AM CST so24 hours are not passed. Any idea?

GetLastTrack might have already started considering the next flight as being the proper flight to consider, even if it hasn’t actually departed yet. If you have a specific flight (and its faFlightId) in mind, then GetHistoricalTrack might be a better function to use.
