BIG UPDATE FOR ME:
Around 9:05 am I tried again on my ipad and was able to enter the virtual queue. I just got through it and made the purchase at about 9:55. I checked the
MDE app and I can see the newly purchased pass in there.
Right after I entered the queue on my ipad, I also entered the queue on my computer. The wait time on that is now 17 minutes. (Current time: 9:59 am.) I just closed that window so that I'm not wasting a place in the queue. But it kept me in the queue until I cleared the browsing data for that web browser.
A few things about my experience:
a) I had been logged in. But when I finally got through the queue, I had to log in again.
b) I had to assign the pass I was purchasing to one of the people in my MDE account.
I chose myself.
It showed that my age is 18+.
But it made me enter my date of birth.
It also made me enter my phone number and email address, even though both of those things should be in there because it's my MDE account.
c) After you enter your credit card info, don't forget to scroll through all the terms and conditions, then check the box saying you agree to them. I missed that step, and when I tried to proceed it said there were errors on my page. Once I did that, I was able to continue.
