Videos Wont Play on IOS 13

So, this seems to be a common problem looking through the forums, but I’m posting here to see if there has been an update yet. I just bought Hook Theory I and II and I am using it on my iPhone 6s+ on IOS 13. My videos wont play when I press the play button, it’s not blank or anything, it’s just that the button appears to do nothing. It is like that in all lessons in Hook Theory I and II. Really disappointed since the videos seem like they would really help out my learning experience. Any help would be appreciated.
