I’m having trouble seeing !buyselltrade\@lemmy.sdf.org from my Piefed.zip and Lemmy.zip accounts in Voyager. Piefed.zip can see posts from 7 months ago, but not new ones and Lemmy.zip can’t even find the community.
If I use an old .world account I can see the current posts in Voyager no problem, so that tells me it probably isn’t Voyager.
I can see recent posts from other communities like !funhole@lemmy.sdf.org so I’m assuming the instance is federating properly.
