In my Deco Parental Control settings, I can add specific websites to block.  This feature is separate from adding a whole category, such as "Social Networking".

If I choose "Social Networking" as a blocked category, how do I know what sites are included in that? Will "Facebook" and "Instagram" automatically be blocked so there is no need to add them indivdually from the included list? 

Also, how do you add a site/service that is not in the included list of Apps/Websites (like Tik-Tok)? 

I wish that TP-Link would publish a directory to avoid the need for extra filtering.
