Can't reply to anyone from kbin.social

You have to explicitly set the language of your reply to English, I find. Since you can't on most apps, you may just be unable to reply from them.

You are definitely seen by kbin.social: https://kbin.social/m/lemmy@lemmy.ml/active has your post. Why do you say you can't reply? Sometimes the synchronizing has some hiccups.
