We apologize for the instability of composr.app and appreciate your patience. We are working on the statistics addon and trying to find an optimal way to store and render data. Unfortunately, we have yet to find a solution that can handle the traffic (and therefore, tens of millions of statistical records) of composr.app. We're working hard on one.
Couldn't reproduce, but the emoticon button for main posting fields was missing anyway. I've fixed that, so I wonder if the issue was somehow you had to paste in the emoticon from somewhere - pasting is notoriously problematic, as it carries styles with it - probably vertical-alignment in this case.
Screenshot is from Compo.sr website, assumed it would be relevant to main release too. I didn't have to paste, I typed :) and it automatically converted it into an emoticon. When going back to edit that post, I saw the alignment for the emoticons was off somewhat.
