Hi when I try and adjust the allow/block list (https://familysafety.microsoft.com/?wa=wsignin1.0) I get an error saying "internet explorer blocked this website from displaying content with security certificate errors" I hit the only button available 'show content' and the site reloads with the same issue.

In Firefox I can access the site but I get an error saying I cant make changes at the moment.

Any ideas ?

Ta

Matt
