My kids Screen Time password keeps resetting every few days

l am using iPhone 14 iOS 18.6.2 (22G100).

My kids use iPhone 11.

I am TRYING to get Screen Time functioning, but keep getting little “gifts” every week.

Either it switches off, or the kids Screen Time passcodes reset to the first code used.

Will not comment the extraordinary complicated options, useless “1 more minute” option etc.

Can anybody please advise how to get Screen Time - an essential function for parents, functioning without having to verify passwords and other settings every morning?

I have scheduled DownTime, limited Apps, blocked after end of usage, etc.

Have watched all possible tutorials, but still Screen Time is a complete frustration.

I will appreciate your help.

Thank you.

Cheers, Katarina

PS: interesting…no Screen Time option in “Topics” (or maybe I have missed it)
