Try to reply to a comment on an iPhone: If you tap on a comment once, the "Translate"/"Stick to top"/Reply/Edit/Delete buttons appear for a very short time but then disappear. It's almost impossible to hit the reply button.
Also, the reply, edit and delete buttons appear behind the social media buttons (Twitter/Facebook etc.).
The user experience on iPhone needs to be improved.
