Latest patch seems to have made it worse. Now not only does it track left and right (hunting) when following a course, it is also porpoising through a range of about 500 feet above and below your selected altitude. Essentially it's unusable.The buggy autopilot in the 747 is infuriating. A320 better but still randomly does what it wants.
) Left it for 30 mins without any joy. Tried several times but it just gets stuck.
I guess something was messed up in the 'secret' WindowsApps folder. Getting access to this seems to be quite problematic but luckily for me both the Launcher and the Game I had installed on their own drive. I copied everything off, bar the WindowsApps folder, and reformatted the drive. I then was able to install the Launcher again so I copied the save files back and now FS 2020 is installing the patch.
