I just upgraded to Android 10. Previously when I began scrolling back toward the top of a thread a button appeared at the top to take me to the home page and a page scroll button appeared in the bottom corner to take me to the top of bottom of the page. Since I upgraded those don't appear anymore, so I have to scroll all the way back to the top of a page to get the home page. If this doesn't make sense I can send screen shots. Thanks!
