My father doesn’t learn UIs, he memorized steps to complete tasks. I guarantee this is how many elderly people operate. If a button’s position changes slightly, if there’s an added pop up or prompt before something he’s used to seeing, it causes frustration and there’s a non-zero chance that he’ll click randomly to make it disappear. So, yes, changing UIs will make pops go mad.
