Hi, Parental Control profiles take effect according to the MAC address. Have you noticed if the kid was able to edit the MAC address of his device?
Deco X50_V1.2-1.4.6 has added WiFi Access Control. It is also suggested to enable "Allow List".

By the way, do you subscribe to Advanced Parental Control?
If the MAC address is always the same, but Bedtime still didn't work, you could refer to this link to submit the Deco APP log:

Thank you very much.
Best regards.
