I think a lot of confusion about the fediverse stems from the fact that most services default to your local instance as front page. I know you can change it in the settings here, but the setting is also defaulted to local, so maybe that one should be set to all, too?
I selected “all” but it’s still showing local when I go to instance’s homepage.
Edit: it works for “subscribed”, but both “local” and “all” show local.
