Tricky to explain exactly. Sometimes the comment button goes straight to adding a new comment rather than the post’s comments. To reach the comments I have to press it again. But because it’s not consistent sometimes I have to press it several times to reach the actual comments.
This messes me up every single time. I click the comment icon to read the comments. But if you look in the post settings (pic below), button 1 is defaulted to “comment,” so I think it is intended to be a “leave a comment” button, as you stated. Which I do agree is counterintuitive. You have to click the body of the post to read comments. I’d prefer clicking the button to take me to the comments section and then have a “leave a comment” button if I decide to do so.
