Apps won’t go into folders?
Did a restore of my wife’s iPad into a new one running iOS 11. Some apps auto populated in the dock for some reason, even though they were not on her shortcuts before. No big deal, we dragged them up to the home screen, and then tried to move them to a folder. That’s a big nope. They do some crazy thing where they “pop” (spread out quickly and translucent) when dropped into a folder and then end up back on the home screen. Things like Home and Clips. I deleted and added them again and no joy, anything that was in the dock after the restore does this it seems. Running 11.1.1.
