Why can’t I move my app icons after the new iOS 12.0.1 update
How do I move around app icons with the new iOS 12.0.1 update?
Question marked as
What's happening when you try?
In my iPhone, running iOS 12.0.1, nothing has changed. I lightly hold my finger on one app's icon, until it jiggles. Then I can move it/them to a different position and/or into a folder.
