I tried to use parental control, and it successfully recorded all network activities. However, the device can still access the blocked content after I blocked them. I tried to restart both the computer and the router, cleaning the cache, but none of them worked. I also closed the Internet Access while that device can still access the internet. I have searched the internet and I found a lot of similar problems, such as [this](https://community.tp-link.com/en/home/forum/topic/157485), and [this](https://www.reddit.com/r/TpLink/comments/16bq0ea/parental_controls_internet_blocking_stopped/), while I can not find a solution. I have checked the update and it is the newest version.

Here is some more detailed screenshots:

In this case, I am wondering what should I do to make it work. If it can not work, is it possible to install a non-offical program on the router like [Open GFW](https://github.com/apernet/OpenGFW)?
