This is very frustrating. The parental controls have never worked. 

I can try adding a website to block, save, then on the device immediately go to the website that I blocked and it shows up.

I can click on history, see the website, click on block, and it says it's blocked, but yet I can still access it. 

This is very frustrating. If I had known this router didn't work I would never have gotten it.

I just updated the firmware 10 minutes ago so I know that is up to date.
