Hi,
When I embed YouTube videos onto my web pages, they look fine whilst in the Pro editing environment, but when I view the live page, a black line appears at the top of the videos.
View in Pro, no black bar at the top:

View on live web page with black bar showing:

It is happening to all videos on all pages. Another screenshot showing a black bar across the top:

Any idea what can be causing this. I’m not making any changes to the YouTube embed code.

Cheers,
Col
