They shouldn't be able to get access to any new internet content once they are in sleep mode. Can you confirm what websites they are accessing and how long after Sleep Mode starts they continue to have access?
This is something we'd like to look into with you in more detail. I have moved this to a ticket with our support team and will reply there.
If they have Mobile Zone installed on their device then the Mobile Data will be filtered in the same way WiFi is.
We have the same issue with our son's Surface Pro - youtube can be accessed an hour after sleep mode should have blocked it.
Can I ask is this for C, T or A's laptop and which day did this occur last?
I have a similar problem to one previously posted. My kids are still able to access the internet after 9pm after sleep mode has been turned on. The age profile controls in settings looks fine with everything a red icon for sleep. The routine for each user is also correct with sleep mode starting at 9pm. Am I missing a setting? Regards, Alan
Please power cycle your home zone box. I've had a look at your account and it looks like the box is a bit confused. A reboot should resolve this issue. Let the support team know if it doesn't fix it.
