I’m registered with lemmy.zip, but I commented on a post in lemmy.world and it won’t seem to show up in the post, although it does show up in my comments list. Do some instances(?) block comments from other instances? Or is this a sub(?) thing?
I’m a pretty new reddifugee and still trying to get the hang of this. Feel free to correct my terminology, please.

If it’s this post: https://lemmy.world/post/39435774
Then your comment is visible. If might have taken a few minutes to federate, is all.
That’s interesting. It still hasn’t populated for me. I’m going to try a different app to access Lemmy and see what happens. I’ve only ever used Mlem, so I have no other reference ATP.
Can confirm. I’m on dbzer0.
Do you use an app to access Lemmy and, if so, which one do you use? I chose Mlem due to its aesthetics matching iOS 26, but if they don’t fix this soon I’ll be switching over to another app exclusively. I’ve downloaded Voyager and Arctic to try out.
