Wanted to run this by folks.
Currently running a separate rack with ap control installed and trying to block the facebook app during certain hours.

Tried selecting tarpit for all items in the facebook category and it seemed to block the website fine but not the app.
Changed the settings over to block vs tarpit and I could see my facebook app feed not pulling in anything. Thought I had something.
Today, with no settings changed the fb ap paused for a few then started loading. Maybe it figured out it needed to use a different server set?
So now I'm wondering what actually is needed to block the fb app.

Could anybody advise what has worked to try and accomplish this?

I didn't find the right solution from the Internet.
