See the screenshots.
Basically, people posting to !alternativenation@lemmy.world from lemmy.world or other instances all seem to work well, even going to Mastodon with no issues.
But lemmy.ml doesn’t seem to be seeing many of the post and is slow to update things like pinned posts.
Nor does lemmy.ml posts to the community seem to be going to Mastodon.
Challenging to build a community on Lemmy when one of the big instances can’t see many of the posts making an active community of over 1500 users seem dead.

“Flagship” in this sense would mean the biggest and most notable, seeing as how the the very nature of Lemmy means there’s no single figurehead or central instance.
Fair enough.
