JUST GOT TICKETS!!!!!!
Been trying since 9 with my code, with the floating code since about 9:45. Was about to give up. I figured I'd give it one fresh start, so I completely shut down my browser, reopened it, navigated to the page, and entered the floating code. The code had been verified for the past 1000 tries but showed no tickets. However this time, tickets popped up and I got 2. This happened 5 minutes ago I just finished paying.
tl;dr, Close your browser, reopen, and try the floating code! Don't give up, I might just be lucky but there is still hope.
