iPad and iOS Video Issues

Hi there,

I'm currently having an issue with videos playing on iOS and iPads. The videos seem to play great, however, when i relaunch the course having exited, the slides and layers misbehave and do not work as they are intended to. Due to the nature of the content, I cant post or upload these files, I was just wondering if anyone else has had issues, and if so, is there a workaround or fix. 

Thanks!

Luke
