The new survey immediately shows up right under the "opportunity expired" message. But when you open the new survey sometimes it immediately returned the same "opportunity expired" message, sometimes had prescreening questions then gave the "opportunity expired" message - it does not make any sense because normally the failure at prescreening would only return either enough participants or not eligible, and then a $0.25 is awarded. Yet on Saturday no matter what scenario it came back with "opportunity expired". I am not in mood to try again yet.

Update -

So today is Tuesday, a couple days after the initial "opportunity expired" symptom. I tried to take survey again. It worked flawlessly on husband's account both from Invite emails and on the site. He even earned the $15 promo (a targeted? offer that if you finished 3 surveys before Feb 20th, you earned $15 bonus).
I then tried my own account. It started fine, working from both Invite and on the site. Was able to finish 2 surveys and a few "enough participants" (earn zero on those). Then the same "opportunity expired" symptom popped up. So I stopped. Hope the site will reset after hours have passed.
