Sometimes my feed just randomly refreshes, losing my position. As in I'll be scrolling, or swipe to go back to posts from a post, but it'll refresh the posts and return me to the top. It feels like a bug, but happens randomly so I can't reproduce.

Maybe there needs to be an option to manually refresh, and every time a user navigates back to posts a little non-intrusive popup displays with "Last refresh: X hours ago" for a few seconds.
