Microsoft FS2020

If there are any knowledgeable folk on here that play this on a regular basis can you help me....I had this game on Xbox PC pass for a few mnths but I did not want to keep paying for the pass as its the only game I really wanted so I bought the Deluxe Version of the Game on Steam.

My problem is not matter what Jumbo jet I fly or the location I pick the plane goes arseway as soon as I hit the Auto Pilot or any of the Navigation aids to fly the flightplan. The sim will just not work....EVER.

As soon as I take off and get to a decent height and stable the plane, engage auto pilot to fly the flight plan the plane instantly starts banking to the left or right and just circles in a loop!!! Its incredibly frustrating and making the game a chore to play. If its a bug fair enough but if its something simple I am doing I am desperate to stop it as the game is unplayable at the minute for me.

It never did this before, but I have not played it since I deleted the XBOX version a few weeks ago so updates have come out.

I have watched about 10 different Youtube vids on each plane and they never have a problem with anything.

Rant over.
