Just in case anyone is using their account here to post to off-instance communities: those posts and comments seem to have a very high failure rate. There is a lot of activity and accounts on this instance. This is to raise awareness, not to pull people away or break up the lemmyverse. Quite the opposite really: there is a technical problem on this instance that might be preventing the lemmyverse from functioning as it should.
Also keep in mind that defederating (blocked instances) will prevent posts and comments from syncing between instances as well.

Correct. I am not testing with any of those instances. You shouldn’t expect that to work at all, but I guess some users might not know.
