I’m wondering as a relative fediverse noob - are there any known issues when federating with lemmy.world?

I ask because I run a They Might Be Giants community there that I created with an alt account and moderate with my account on this instance, in part because as giant as they may be, I feel like a They Might Giants community doesn’t fit this instance (if I am wrong, might consider migrating it).

I made a post ~14 hours ago and it still hasn’t shown up on other instances. I’m guessing it’s either lemmy.world is a ginormous instance or it’s still on 19.3. I just find it weird because I’ve made posts without problems before.

Anyhow, glory to the admins of this instance; they honor their houses.
