Failing Validation. Unsure what to do

I have the right aircraft (not default). Can this be fixed / bypassed?

Sometimes aircrafts get updated with MSFS release and their stats has to be updated on Aviatife as well before they can be flown.

Could you post which aircraft you were trying to fly and the whole validation screenshot?

If you have Discord, you can also directly post it in #aircraft-mismatch channel.
