Whenever I try to watch an ad to get that l2 access it says "video cancelled" without even opening.

I'm having the same problem, I do think it's a bug because I've tried several wifi connections and my 3G and it still doesn't work.

Update: do you have multiple devices? I managed to get the ads to work on my tablet but not my phone so it could be a multiple device problem, if it's not a bug.
