Make sure you’re changing the correct string. This one is js.footnote.add. There is a similar one under discourse-ai, but that’s used elsewhere.
@keegan looks like we accidentally hardcoded this one?
These three are considered to be part of the post content. So the translation is only applied when the post (or ‘small action’) is created.
Will be fixed by UX: Fix translation of post.in_reply_to by davidtaylorhq · Pull Request #37175 · discourse/discourse · GitHub. Thanks!
