Select YouTube from the Policy menu.
STEP TWO
On the Videos tab, paste the full YouTube video URL (e.g. https://www.youtube.com/watch?v=…) into the Video Url field.
Paste the video URL into the Video Url field.
STEP THREE
Click the Block button below the field to add the video to your Block List.
Click Block to add the video to the Block List.
STEP FOUR
The video now appears in the table below the buttons with a Status of Block, confirming it is blocked network-wide.
The video appears in the table with Status: Block.
STEP FIVE
To remove a video from the Block List later, click the trash/delete icon in the Actions column for that row.
Click the delete icon to remove a video from the Block List.
