I’ve seen about six that went through, there was an issue with the payment program that was fixed at about 2:45 CT this afternoon, you might have to go back to the release for payment stage and try it again.
I helped a new TD with an NCD event, his first. It went smoothly until the payment step. After fixing the tournament name, he applied the coupon which resulted in a $0 fee. But next he was shown a fee without the code. He’s emailed the office. Hopefully, he didn’t use his one chance at the coupon because it didn’t look like it was seamless to me.
