Wish I had the same success stories you did. I'm on the West Coast and the app went live around 12:06 for me. I'd already done the pre approval and gotten confirmation beforehand, so when I loaded up the app it went straight to the checkout page. It then loaded the "Choose Delivery" method, and I opted for the home delivery, which was a button that said 'Nov 3'. Gave it a tap and I got the order number and everything. Thought all was well. I wake up and see my confirmation email came in an hour or two after the order had been submitted, however with a 2-3 week delivery aimed for Nov 17-26.
Had I known it had slipped or the button hadn't shouted "Nov 3" to me I would have opted to pick up in store, as I will be moving in a few weeks and am concerned about being able to change the delivery address on the order (it's not currently letting me). It really blows, and not really sure how to approach this beyond canceling the order, and putting one in for the 5-6 week delivery window Apple is currently estimating at my soon-to-be new address :/
