What some of us were referring to wasn't that we didn't have the button on the home page but rather that it was greyed out (instead of brightly colored) and didn't work after the first survey accessed using the button. Did your button "stay lit" after you came back from finishing a survey? Anyway, it's new for those of us who just got that notice.

FWIW, I don't think I had a limit, either (or at least it was higher than 3, as I've done more at a sitting).

Anyway, a lot of people apparently have different configurations or limits, accounting for different experiences with the site.
