Here are some UX issues I've encountered with the mobile app (iPhone 11/iOS 15):
* The app seems to operate as a mini web browser rather than a native interface. So what is the point of having the app? Would be good to eventually transition to a native app.
* The back button "<-" does not work most of the time, so you can only really do back swiping.
* While scrolling, because you are effectively browsing a web page, text can inadvertently get selected, which is quite disruptive (see screenshot).
* While scrolling through shares, if you are too slow, a "quick view" popup will get in the way and disrupt your scrolling (see screenshot).
