YouTube render problems. Session closed

There is a known issue of rendering YouTube embedded videos. Because of the infrastructure limitations, we hit a problem that some screenshots are not rendered properly.

For example, you can see something like

Session Closed error

 

The problem is with YouTube embedded videos.

So if you face such an issue you can have a workaround by hiding embedded videos with CSS:

.wp-block-embed-youtube {display:none;}
