iPad Mini, iOS 18,4.1, Safari. In the past week or so, when I look up a stock, the resultant screen soon starts vibrating (or jumping) up and down. Refreshing doesn't solve it. Pressing my stylus in seemingly the right place doesn’t at first, but then does stop it…until it starts again. Doesn’t happen on the main Finance page with “My View.” Can’t tell if Yahoo or Apple.
