Posts not appearing in communities when other group actors are mentioned.

Tried making a post (link below) to a lemmy community while also mentioning two other groups. My post never appeared in the Lemmy community.
This seems like a bug, when I tried posting to two lemmy communities at once the first went through, the second did not.

Does anyone know what’s up with this?

    Always post in this format:

    Thread title
(Blank line)
@Lemmy_community @Friendica_group/Hubzilla_forum/(streams)_group @Guppe_group (optionally more Guppe groups)
(Blank line)

      @JupiterRowland Ok but does this actually solve the issue of not being able to post to multiple Lemmy communties at once? As far as I can tell when you make two mentions to Lemmy communties the first one will go through, second one will fail. If one is a guppe group both will fail since Lemmy only allows one post to go through for some reason.

        No. You can’t crosspost to two or more Lemmy communities at once. AFAICS, that’s fully deliberate and intentional by design to keep people from spamming Lemmy with mass-crossposts.

        What it fixes is trouble with crossposting to Lemmy, Friendica/Hubzilla/(streams) and Guppe groups. You can’t mention these in any order you like. You always have to begin with one Lemmy community. If a Lemmy community is not mentioned first, it will be ignored, no matter what is mentioned first.

        Also, apparently, mentioning Guppe groups before a Friendica group, a Hubzilla forum or a (streams) group doesn’t work either.

      Essentially, the title of the post/thread comes first.

      Then comes a blank line.

      Then come the mentions, all in one line. They must always start with the Lemmy community, and you can only mention one Lemmy community. If you want to crosspost to a Friendica group, a Hubzilla forum or a (streams) group, it comes next, and AFAIK, that can only be one, too. Guppe groups come afterwards, as many as you want.

      Then comes another blank line.

      And then comes your actual post.

      Another blank line.

      Lastly, hashtags so that Mastodon has them where it expects them.
