Hello The Daddy UK,
Welcome to Microsoft Community.
Thank you for your support of Microsoft products. I fully understand your concern for your two children as a father.
We do receive a lot of feedback from users about the family group and family security features, such as not being able to add a child's account to the family group, not being able to delete administrator permissions, or not being able to perform any actions, such as "It's not you,it's us", etc.
Microsoft's servers may be experiencing some temporary glitches that are causing the problems, including the fact that the family security app's display location is no longer updated.
I deeply understand the inconvenience this problem has caused you. Microsoft is aware of this problem and has arranged engineers to investigate the problem. Please wait patiently for the problem to be fixed.
Here is a small suggestion I can give you. Perhaps you could replace the home safety feature by calling your child at the same time every day.
Please allow me to apologize again for the inconvenience.
Best regards,
Mitchell - | Microsoft community support expert from MSFT
