Screen time on - child removing apps from Home Screen. Help please!

We have used screen time for many years to stop my son with SEND deleting apps.

However there is now the option to remove apps from the Home Screen. Screen time does not override it.

This changed in a recent update.

So Screen time is on - including not deleting apps.

You can still hold and remove apps (ie delete) off the home page. They remain in library where you have to painstakingly restore each one.

It’s a nightmare as every time I pick the iPad up he’s removed them all.

He is home educated so I need to leave him with educational apps to explore whilst I do jobs or work. He can literally have them deleted in seconds.

I tried the Quostodio app but that still allows it to happen.

How can I stop my child removing apps off the Home Screen please?
