It should work if you post using a Lemmy account. However, if you use a Mastodon account it will show as “#” which is not working as expected right now, someone has been opened an issue talking about it: github.com/LemmyNet/lemmy/issues/3789

Edit: After reading your comment again… oops, I think said too fast.

The situation above only applies when you try to post to Lemmy Communities, and also, I just tried it by myself, hashtag in Lemmy seems won’t work.

Testing-ground: lemm.ee/post/5513264

Usually, the hashtags in a Lemmy posts is a hyperlink, i.e. #hashtag, for example this post posted by a Mastodon account:

lemmy.world/post/3754328

I don’t know if hashtag (strings) works on Mastoson, because it might be processed (e.g. HTML character-escaped) when transmitting to another instance, and the testing community i posted is not federated with other instances.
