I am a brand new user of AM 3.7 and Beta 4.0 so I am the first to admit that I don't know, what I don't know!
That said, I thought I would PIREP that my primary flight controls randomly will lock up/freeze as I fly around in FS2020. The first few times this happened, I would restart/reboot. However, earlier today when it happened, I discovered that if i tapped a new/different knob on my touchscreen monitor the flight controls would magically jump back to life! I completely understand that this is a BETA version, and that bugs are expected and hopefully will be worked out down the road. I just thought I would share something that allowed me to work around in the meantime. Good luck to all!
