I can't block reddit on my AX50 / AX3000. I've tried adding both www.reddit.com and reddit.com to the keywords list; neither work.

Other URL filters do work; like "www.pinterest.com" for the website Pinterest, as well as urls that do not already have a built-in keyword, like "www.espn.com"... although in neither case does neglecting to add the "www." before the url work to block the sites, unlike the instructions given by the UI.

Why can't I block reddit?
