I recently upgraded to MCU2 and noted the software version was 2022.4.5.3. After I got the car home I saw that there was a new update available, and after I installed it my app showed my recent update as 2021.4.3! I was perplexed. Then I received notice of a new update which I installed and my car once again showed the most recent update as 2022.4.5.3! Can anyone explain? TIA
