No If you look at "By policies for it to block like on MOBILE, website on browser and "youtube" app."
I do have it blocking websites eg. "www.youtube.com" on desktops, but you can still access youtube through youtube app on mobile devices or by just doing "https" on desktops, it blocks "http" but not https... you can access any site with https I don't want that. It doesn't block anything on mobile devices. I use ESET at the program but its hard to use and it doesn't block mobiles because it need to be installed on a mobile device in order to work
