cant search using tail number with the GetLastTrack

Hello,

Im trying to use GetLastTrack to search for a plane/flight using the planes tail number. However it isnt working. The GetLastTrack function works with the flight number but nothing else.

Is this a known issue or do I have to do anything special to get that feature working?

Thanks.

GetLastTrack only supports using whatever identifier it was being identified to ATC as. If it was operating under a callsign, then you should use that. If it was operating as its tail number then you should use that.
