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.

I wonder if this has something to do with the Activity Pub Protocol? But then again I don’t think I have ever heard of any issues like this on Mastodon, or any other fediverse instance that uses Activity Pub.
