Hi jpdelta12,
I have had the same problems as you.
Interestingly, the first flight I did from LAX to MEL after the last update had no issues.
But, the last two flights I have turned on the Autopilot and it has disengaged V/S and activated VNAN and I then cannot disable VNAV.
I have found a work around but it is not ideal.
When engaging autopilot immediately after take-off I have been able to select any buttons.
I also had to start the flight from the runway with the engines already running.
Cold and dark starts from the gate lead to the aforementioned issue.
I know this might not be ideal but it makes the plane flyable.
