I don’t doubt that it is possible, but it is certainly not typical at all.Not trying to add fuel to the fire, but from this data point, when I picked up my MY it was on one software version, and by that evening I had the newest software version out.
The only time I had a delay about getting software quickly was when I opted in for Beta FSD, biggest mistake of my life, I was blackballed for over a month, but that's a whole other story.
