Thanks so much Chris! I had the Apple Collections light blue Live Wallpaper (the one with falling blurred circles) on my Home screen and a photo as lock screen before the last iOS update, but both were updated to a static light blue background after the iOS update. When I tried to reconfigure it as it was before, I found that Live wallpaper is no longer allowed for Home screen, only for lock screen... Guess we are creatures of habit, so I'd like to have it as before but for the moment I'll have to settle for the photo/static Home screen. Thanks again for the useful info and links!
