Update does not happen
Four days ago the notice of an update that would be done overnight appeared. It is on the screen every day, several times a day. I have automatic update activated and it still does not occur. I also leave my iPad plugged in overnight. I go to settings and see there is an update available but when I tap “install now” nothing happens. Why does this keep saying it will update automatically and it doesn’t and it won’t let me update manually. Any ideas?
