Sometimes it clears up even faster. Had it happen this morning, with not one but two different surveys, but by early afternoon newer surveys had already pushed the problem surveys down and off the page. Interesting that both surveys were from ssisurveys.com.

I've had some inconsistent luck with two approaches other than waiting it out: 1. If you're taking the survey on a computer, try it on a mobile device. If you get lucky, the particular survey doesn't work on mobile devices, and e-rewards will move you on to the next survey; 2. If you've had no luck clicking on all the other surveys on your dashboard, go back to them and click several more times. That has occasionally given me access to another survey, but unfortunately doesn't knock out the problematic one.
