Hi Dave,
I hope you are okay. I am contacting you because I have tried to perform a flight on MSFS 2020 today between RJCC and RJAA. Unfortunately, when I tried to request the clearance from ATC, I receive a message saying that it appears that my flightplan does not originate from this airport but it definitely does. I am not sure if this is a bug from Pilot2atc which does not recognise the airport as being in the database?
Kind regards
Martial
