I blocked the app but it is still on the screen (iOS)

When you use internet-based app blocking, you disable internet access for the apps. It means that they will still be on the screen and your child will be able to open them, but new materials won't load, as if the device has no internet connection.

If you want the apps to be hidden from the screen, you need to set up our Advanced Features.

You can check the installation process on this page:
