as was suggested in one of the threads, when you get the points added by poll, leave that window untouched and open another tab for myrewardzone.com and redeem/print certs right then. you *should* be able to redeem for the max points you see after poll.
This worked for me, was having the same issue of points showing on Facebook but not the website. Did this after doing the poll today and was able to generate a $15 reward. 500 of which were from a csr that added them to make up for 200 points lost because of the point adjustment.
