Just ordered my tickets. Details:
I signed in via the hyperlink that was emailed to me this morning. It took me right into a stadium overhead view
Go to the upper-left corner to indicate how many seats you want (2 or 4). If you hit the "+" sign and end up on 1 or 3, it will show that no tickets are available. So make sure you choose 2 or 4
All sections still had seats when I ordered, so all sections were blue (not sure what it'll look like if a section is all picked over)
Zoom in and pick the pod of seats you want. In my case, I chose 4, so it illuminated available pods of 4
Click the desired pod and add it to your cart (it's possible that the pod you're looking at will be added to someone else's cart while you're looking at them, so decide quickly!)
Purchase them in the given 10 minute window
Good luck!
