Ever since I installed firmware 2020.8.1 my 2019 Model X no longer properly locks the car, shuts off the displays, turns off the A/C, or pauses the audio once I put the car in park and exit the vehicle. The driver's door closes properly, but the car does not shutdown properly. I get similar behavior with both "walk away locking" turned on or off. It occasionally works properly, but most of the time it does not.
