Hello, 

If the adult websites are actually not blocked when you choose "pre-teen" filter level, please go to https://global.sitesafety.trendmicro.com and enter the URL of the adult website, then you will see if that website belongs to an adult website or not.

If you find that a website is classified into the wrong categories, please submit a reclassify request to Trend Micro.

However, if the website belongs to the correct website category, but it is not blocked, please show us the Parental Control settings page on your Tether app as well as the firmware version of the router, we will try to confirm.

BTW, can I have some examples about those websites that cannot be blocked?

Thanks.

Something very weird,

This is the most popular adult website & it's already classified as shown below but I still able to access, in the first try it's shows error (ERR_SSL_PROTOCOL_ERROR) but after reloading the page more than one time, I was able to open it.
