A320 in MSFS 2020 is unflyable

So after the last update 3 days ago flying the A320 has been nothing but a fail. You cannot fly the plan realistically as far as navigating. Entering a fight plan in the MCDU is pointless. If you don't change anything while enroute, there is no problem. However, if you want to bypass a waypoint and go direct to another, the whole autotpilot nav system goes haywire. This was also a problem prior to the update, but you could work around it using heading and or a direct command. The aircraft will go direct to the waypoint selected(sometimes), but when it reaches that waypoint, instead of continuing to the waypoints past the waypoint you were going direct to, the MCDU reverts back to the original flight plan and turns the aircraft back to the departure airport. I know this was a bug, but you would think this would have been handled in that update. Obviously not. Could someone enlighten me as to how this happens. Folks are paying their hard earned cash to play this game. And I know there have been many complaints concerning this.
