My child is bypassing screentime limits by restarting the iPad Air?

Hi

I found out that my child is able to bypass screen time limits by just restarting his iPad Air.

I found other similar threads here in this forum, YouTube videos and website giving various tips and tricks on how to bypass screen time.

Frankly speaking, (and I'm working myself at a software company) it's kind of embarrassing that Apple is not able to simply shut off apps or the whole device if limits are configured. Can this be so hard?

We all have responsibility for our kids and I thought screen time would be a tool which supports parents, but obviously this is not the case.

Disappointed regards
