So I did everything asked for at u2.com 2 days before the Sunday deadline at 7pm pacific time and still didn't receive a presale code. Set Up Complete , Email verified, Ticketmaster account tied to U2.com account. My Priority Access Group reads INNOCENCE
So I sent 3 emails as the start time of 10am approached nothing... Tried calling the u2.com help line 1-855-867-5297 busy for 1 1/2 hours after the 10am start time. Finally at 11:30am the line rang and I was put on hold for more than 20 minutes, then someone came on the line and took my info and gave me the code over the phone.
So don't give up if this happened to you.
