When Screen Time comes out of a blocked period on Apple devices all of the app icons get arranged alphabetically (due to a limitation of the Apple platform) which can be super annoying!
Fortunately we have found a cunning loophole that will stop the layout being messed up. We call it Layout Fixer and it’s easy to install but a bit quirky. If you do any re-ordering of apps during a blocked period then Layout Fixer won’t work and your apps will get messed up again.
