Dailymotion Won't go Fullscreen

[TheFadedSpade]

So I've been trying to watch videos from Dailymotion embedded into a site. When the video starts playing I click the fullscreen button on the bottom right and it doesn't go full screen. The button glows so I know it's registering my touch, but it doesn't go fullscreen at all. I can rewind/forward and I can pause/play but I can't go fullscreen. I'm on Android 5.0 (not the latest one) if that helps. Any ideas?
