Hi,
Welcome to our community! 
I’ve just tested the video, and it worked for me. Could you test it again in your browser? There are multiple reasons why a video doesn’t work:
- Server issues. Try again in a couple of minutes.
- Browser issues. Clear your cache.
- Browser issues. Test another browser.
- Broken video. If you tested the three things above and the video still does not work, please let us know, so we can check it. Maybe it is broken. In that case, our team will have to fix it as soon as possible.
Did this help?
