A quick observation. When clicking on a link in "My News Feed", it automatically takes me to the end of the thread, even if I've never seen the thread before. This forces a manual scroll all the way to the top to view unseen posts.
For reference, I'm a heavy phone user. So I'll add my vote for turning on Tapatalk. It's familiar and allows easy and quick jumps to my other forums of interests, particularly gun interests (although I spend most of my time here).
Also typing this, I notice that certain keyboard strokes such as the left/right cursor movement, sends the entire screen to relocate and moves the active type window out of view. Requiring a manual scroll back to find the active cursor. On an iPhone 7+.
Not trying to be a pain, just making notes of reference for the debug preocess. Hope they help fine tune my favorite place to spend time.
