I don’t know if it’s related but I have a hunch that it is…
Using the MSFS ATC, I often hear ATC say to other aircraft nearby, “traffic at 12 o’clock, FL350” when I know I’m at FL 360, for example.
I know they are talking about me and the flight level is wrong.
At least now ATC doesn’t complain that I’m at the wrong altitude.
Something is still fishy with altitudes.
