I can't seem to get the embed code to work. Here's the iFrame that needs to be embedded:
<iframe src="//flipquiz.me/review/54450/" frameborder="0" width="100%" height="600px"><a href="//flipquiz.me/review/54450/"></a></iframe>
I believe the problem with your code is that the url for your Quiz is not on a secure server. You can read more about that here: How do I embed a Guides lesson inside a Canvas course?
The upshot is that you probably need to talk to flip quiz support about providing the lesson on a secure server (https).
I hope that helps, Kate!
