Micoroft Family Activity reporting double the screen time for child account

I would suggest contacting xbox support as they may know more about the problem than us and may have a known solution:

Are you sure no on else has access to the account or knows the password ?

ChiefJoboo: But even if he was using a separate guest account, that wouldn't show up in the Family activity totals would it, as that account's
not part of the family?

In any case I have been through all the steps on that page and none have worked. I've watched him and the screen time limits are working fine on the Xbox - it tells him when his time will end, and it ends accurately.

He is also not using his account on the Win10 laptop, so I know it's not simply a case of two devices being used.

I've just run out of ideas as to how to reset this so it starts working again.

I'm certain. But how would this result in the double reporting in any case?

With the latest update of Windows, you're able to set up one schedule that'll apply across all of your child's devices. This means if you give them five hours in a day, they'll have five hours between their Xbox One and Windows 10 devices.
Otherwise, time gets tracked separately, so 1 hour of screen time means 1 hour per device. That may be the cause of this issue if they are on another windows device on their account.



Have you checked to make sure your child is not making other accounts to get around the screen time limits? You can make sure that can't happen by changing this setting on the console:

• On your Xbox, press the Xbox button, then select
  Settings > System >
  Signed-out content restrictions. Then create a guest key and turn off
  Let people download & make new accounts. From then on, you'll need a guest key to add new accounts.
