Content filtering not working on XG

Hi, I am running Sophos XG Home SFOS 17.5.5 MR-5

First question: Can you run clientless users on devices such as iPads and have them content filter?

Now my issue:

I am trying to create a web filtering policy to keep my children safe.

As you can see, sexually explicit / adult is blocked

This is the rule (ID9) the user in question is "dan" the others are clientless users and forms part of my first question.

Once again Rule ID 9

Here's user dan visiting sexually explicit websites and its allowed

Any assistance is greatly appreciated.

Thank you!
