Hi..I am not still having this particular issue as it seems to have resolved on its own, although I think it was tied to GSX. The issue stopped when I removed it.
But now I cannot, for whatever reason, taxi my plane. I am using TCA Sidekick so not sure if that is an issue with that peripheral. But I cannot taxi left/right with any plane.
I often cannot click on managed heading or climb buttons....the push/pull buttons won't work.
I have also had trouble getting the external power and batteries to work, even though I can turn them on. Doesn't happen every time though.
