Maybe it's a staggered rollout to not overwhelm the servers?
I got updates last night and have FSD trial through July (1 month free plus 3 months using referral bonus). Unfortunately I can't use it since cameras are calibrating. Calibration has been stuck at 80%, so I went for a drive yesterday, and now calibration is at 79%, LOL. From what I read on forums, it can take up to 500 miles to calibrate, so I might run out of the free trial before calibration completes.
