Why is the video in Dawn theme not loading without refreshing?

[norinorinori]

Hi there, we are using Dawn theme and we have uploaded YouTube videos to the product photo. (It's the third photo). However, when we press play, it says 'This Video is Unavailable.' Only when we refresh the page, does the video work again. Can you help make it so that the video can play without refreshing the page?
