My replies don't show up as replies when I reply on mobile

I typically go on the forums on my phone. I also happen to like Discourse’s reply system very much. However, whenever I tap the reply icon and post a reply, there is no visible indication that my post is a reply; the recipient’s pic doesn’t show up in the upper-right corner of my post.

I don’t know how deep this goes—like, is it just visual and is still considered a reply, or is it not being treated as a reply at all and the recipient isn’t getting notified, etc.?—but I figured it would be worth bringing up.

If my browser info would be of any use, here it is: Google Chrome (stable branch), Google Pixel 2 XL (Android 9.0).

(Not sure if this is a site-specific issue or one with Discourse in general.)
