I've disabled all categories and smartplay but still allowed YT. My goal is to have YouTube videos only available if they've been explicitly added by me. This is mostly working, but there are some videos that are categorized as "Unknown" and they are still allowed to be played.

This video specifically comes up "Unknown" and is allowed by the the filter: https://youtu.be/WmWCAujwbrE

Can we add an Unknown block rule, or just not allow these by default?
