Why isn't parental controls blocking gameplay on days it should be blocked?

Solution 1:

4 things could have happened

1. They know your password and changed the settings
2. You could have not hit save so when it turned off it got deleted
3. They didn't play,they may have watched Youtube or something unless you blocked everything after 4 hrs
4. You have a good kid that didn't want to annoy you at work and went and did something else

Solution 2:

I just did this

In the Microsoft Family Live web page

1. Remove all the allowed schedule blocks and set all days as blocked

In the Xbox One console

1. Change my passkey
2. Delete and add new guest passkey
3. Double check that my account is Locked (requires the password to sign-in and to when switching from another account to my account)
4. Remove all the accounts (except mine)

5. Add the child accounts that are included in the family group

   At this point, before the account setup process starts it showed the notification that the account has to request permission. The permission was requested and I allowed 2 hours. As expect after this time, my kid reported that the end allowed time notification was shown.

So far, so good.

Later this night I will change my Microsoft account password and later this week I will "audit" the Xbox One console settings.
