I'm sorry others had more trouble than me, however...
I started the Extra Regret-it Rewards at a couple of minutes after midnight. All of the gift cards for the program were shown in the Redeem section immediately, all $5. I didn't see anything that I liked, however, I pounded away on the videos and quizzes that would come up after refreshing page after page and opening what I could find from several different parts of the redeem offers, and multiple EC screens.
I was hoping that something that I wanted would show up before I completed the tasks at around 12:20AM ET. It was a struggle to finish but it worked from me.
Nothing new came up for the Extra Regret-It Rewards, so, it was a waste of time. The early bird gets the, well...<nothing>. All of the "rewards" were available to me after completing the tasks; but, there wasn't anything I wanted.
Note: I use the Chrome browser on a laptop.
