I have to agree 100% with both you guys. The control changes don't make ANY sense, and I am also having troubles setting up they way it was. Supposedly we can use the 2020 default keyboard, but it does not work for me. Also, I rarely use the keyboard, I have (had) most of the basic actions required for simple GA aircraft on my HOTAS (X-56.) And no, I haven't been able to program the "D" and "B" keys to my stick. They did work in 2020. The default settings for them are completely different, and don't seem at all intuitive. I was able to put some of them back, but now I have totally random button presses going on, even when I am not sitting in front of my screen. And they are TOTALLY different from the ones I was fighting in 2020.
My Tobii is not working well either. Constant drift to the right, very little vertical movement, and other problems. I disconnected mine after a couple days. The changelog for the latest update says they "fixed the CTD when adjusting the Tobii in the settings." I haven't reconnected it to check-see if it works.
