Details for assistive touch scrolling - how to use grey dot that appears when you select scrolling commands
I've been trying to use assistive touch to enhance my scrolling capabilities, but I can't figure out how to use the grey dot that appears when I select a scrolling command. The dot does seem to control scrolling to some degree, but it doesn't work consistently, and continues to follow my finger around even after I am done scrolling.
I have "scroll to bottom" selected as one of my assistive touch menu items, expecting it would give me an easy way to get to the bottom of, say, a page in the Wikipedia App. But the grey dot appears, if I touch it, it scrolls down but not necessarily to the bottom, and then it keeps interfering with page navigation afterwards. I haven't been able to find anything explaining how this works. Thanks.
