For such a large company as reddit the app is incredibly poor. It is riddled with frustrating bugs that have existed for so long but have yet to be addressed. One key issue is how much the app struggles to load any videos or GIFS, which is a large bulk of the content you will find on reddit. Other frustrating issues include sound being played from videos that aren't even on your screen, so you have to scroll to find it just to turn it off, or the scroller just randomly refreshing itself.
