Of course that was a while ago, so things may have been fixed.  However, I participate in a forum where the topic comes up occasionally as to why someone can't get it to work.  If you can go to a test site, such as test-ipv6.com and it works, then I guess it has been fixed.  If all is OK, you should get 10/10.
