Not sure how people get in so early. The last few models I've ordered using the app I never get in until atleast 10+ minutes after the slated release. I started closing/opening the app well before 12:00. Ended up getting through around 12:10 but had to repeatedly keep trying to verify my account to AT&T, continuing the checkout, and complete my order via Apple Pay. Nov 17-24.
Same thing every year, I think I'm going back to orderering through AT&T next year since I always used to be able to get release day phones.
