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.

I’m assuming Boost and Jerboa are android apps. I couldn’t find those, and I tried Voyager today and I’m not feeling the set up. It’s basically the same as Mlem, but feels clunkier and isn’t as easy for me to follow. I do appreciate the reply and suggestions.
