Can't proceed past "congratulations" "go pro" advertisement

After completing a review session sometimes one sees fireworks and then an ad about upgrading to pro. The ad is fine, I understand the need to monetize. That being said - there’s no way to close the ad and proceed to the next test without typing in the website name again. There’s no X (well there is, but its for the course and doesn’t work anyway) no “close”. Clicking outside the advert doesn’t do anything. The only option is “Claim your reward no” or “Go Pro”.

Browser: chrome - mac (latest)

Steps to reproduce:

  1. complete a review session
  2. see fireworks - on seeing the fireworks click the X in upper-right to close them
  3. see advert for pro
  4. observe no UI to close advert so you can click the next review/learn more button

Ya, this is annoying. I think pressing “Esc” closes the popup, but I doubt most people know that.

@Joshua, this really is kind of an issue. Any chance you could take a look?
