It was a terrible problem and the only quick fix for me was to physically exit the vehicle and then climb back in. No more problem until the next use of the Model X.
Another issue was the spoiler not dropping with the "lock" press of the key fob. I had to return to the car for the key fob to be noticed before the spoiler dropped down.
I called Tesla last night and discussed this problem at length. I did get the new version of software today, so I will be checking if there are any remaining bugs when I next use the vehicle.
