Tried to block internet access for one of my iPhone for testing purpose (it has dummy SIM means no cellular data)

Enable Parental Controls (i.e it is ON)

Choose a specific home device that I want to block then choose option : "Always" ,,,,,,,,,,,,my router screenshot same as the link above

Click Apply

But it didn't work !!!!

Tried another iphone same issue

I have latest firmware and I did restart the router as well

Am I missing something ?

You've asked this exact same question in at least three other forums, all on 18th August, and had responses with regard to the solution from all of them. Why are you asking it again here?
