Hallo,
I have (only with V3, V2 works flawlessly) the problem with some planes in MSFS 2024 (for example Inibuilds A340, iFly 737MAX) that I set the transponder mode normally in the plane, but the mode shown in Pilot2ATC only switches between Standby and Test. A change in Pilot2ATC directly is not possible as the value is being reverted instantly. I searched the forum but didn't find any relevant topics. Is this a known problem or may it be related to my setup? Thanks for a short feedback and best regards from Germany, Alexander
