Autoplay Loop for iPad 2 - won't loop

Hi - I am having difficulty with the Autoplay Loop for my iPad 2. I have gone into the settings on my iPad, enabled Autoplay, turned the Loop on. It plays Autoplay's once, then stops. I've reset it, closed the Prezi app, you name it. I can't get it to loop. Please help! I spent a ton of time creating the Prezi's for this very purpose!
