Tether NOT BLOCKING sites, online gaming and connections already established on a PC
My Archer AX55 is not blocking some already established connections to my child's Windows 10 PC (software fully updated) when I select BLOCK or if their screen time runs out. If they are already connected to discord and having a conversation, that connection never gets blocked because it's already established. I'm seeing the same thing with online gaming sessions and YouTube videos that are already loaded and they don't get blocked even after the buffering runs out. I've tested this and I do see that new connections get blocked, such as new YouTube videos, pings, newly loaded websites.
How can I resolve this issue? It's a problem that my child can continue to use their computer (discord conversations, online gaming sessions, watching YouTube pages that are already loaded, etc...) after their time expires or I block them. Tether is not fully effective with this flaw.
Please help.
