I see, you're on Piefed. I've heard of Piefed. I'm still relatively new to the Fediverse. So my understanding (correct me if I'm wrong) is that Lemmy is like a free/open source clone of Reddit (I mean, it kind of is), but Piefed is like a fork of Lemmy. Different people make it, but it's similar enough that users can fully interact. However, not everything may work 100% between them.

So when I saw your post, I saw the space where a link would go, but it was blank, there was nothing to click. On your side it probably looked fine. So the issue is technically on my end since you didn't do anything wrong, the software I use just didn't display it properly. Unfortunately, it's down to the developers to fix stuff like that.

The instance I'm on is considering a Piefed server and I've heard nothing but good things. So I'm looking forward to seeing if I can migrate/clone my account to their Piefed instance.
