ScreenTime not working, randomly resetting

I have reached out to technical support for assistance, but ScreenTime is consistently resetting itself. I have gone through blogs, Apple forums, etc. to address this issue, but nothing is working.

I set up ScreenTime and without fail the Content Restrictions, Schedule, and sometimes other settings will completely reset, sometimes within minutes/seconds of setting this up. I have factory reset all devices and reinstalled OS. Also, the ScreenTime is will only occasionally enforce app limits.

I have reset the passcode so many times, no one knows it but me. ScreenTime used to work flawlessly and was a wonderful tool for parents. I am not sure what happened, but now my life is a living **** with not being able to regulate electronic usage in our home.

All devices hav latest software. Have already checked your blog.
