I have had a look into your account and the logs associated, and I cannot see what explicit content you mentioned. Do you mind letting me know exactly what content was allowed? Or give us a ring at 1300 398 326 and ask to speak with Zac and I will be happy to help resolve this issue.
I've tried accessing sites that I have blocked on my son's laptop, eg advertising and alcohol and I can still access them. There doesn't seem to be a final step in the process.
This is occurring on iPhone and laptop
I can see under your age profile controls that advertising is enabled except during sleep while alcohol is blocked all the time.
I've created a support ticket for your issue and will contact you shortly.
Best regards, Timothy MacLatchy.
I have a similar issue. I just tested all browsers, and firefox allows acces to adult sites. The protection works seems to be working well on Edge and Chrome.
