I've been having exactly this problem on both the web client and from Memmy, an iOS client, while trying to reply to this local post. It was posted by someone from a Mastodon domain, so maybe related to @bsammon's idea.

I've been running into a similar issue. I click Post and get the activity spinner on the button. Then nothing. I've had this occur on three or four threads. Closing the tab and opening a new instance / reloading the page in the existing tab does not solve the issue. It appears to be local to specific posts / threads. I haven't tested to see if I can reply to a different comment on the affected threads.
I ended up sending a DM to someone because I couldn't reply in the original post. I linked to it. I just confirmed that I still couldn't reply to that post. Here's a screenshot.
Okay, it appears to be a very specific failure--I was able to respond to other comments in the thread but not the one posted by KD.
Now I'm thinking it's probably a Mastodon-to-Lemmy thing. KD's comment (appears to have) came from Mastodon.
Let's do a test
My first successful attempt at commenting on a comment 🎉
Seems to work on my end...
Looks fine to me too
And my axe!
Yeah... it works just fine in this post/thread. Anyone try it in the chessboard thread that I linked in my original post?
