Hi, not true that other users have no problem. I have it, and I am quite certain that all P2A and ToLiSS A319 users have it, at least that's what it seems to be the case by checking ToLiSS's xplane.org support forum. In my case, when I change the frequency manually in the aircraft radio, it automatically changes in P2A as well, but not the opposite. Would be nice to have this resolved between the 2 devs. Thanks in advance!
