I was on right at 7am also, and it showed booked For 1/18/20. I almost freaked out but them remembered several on here said it may not open right at 7am. It was weird because the day was not grayed out way before 7am, but when I tried to book earlier than 7, it let me get all the way to the last screen, then gave me an error. Right at 7am, it showed a black mark through the date, as if it was all already booked. I was fuming for a second, but decided to take a breath and hope that this was going to resolve itself in a minute or two. And it did. The black mark went away at 7:01am and then I was able to book. Now to do it all again tomorrow for 1/19! Good luck all!!
