I created a Lemmy instance. Making posts, comments, all that jazz seems to be good. Sign up works. Other functions work. What doesn't work is federation. The instance is been alive about about 24hours and I don't see anything in the all tab. Directly going to communities via a url like "my.lemmy.instance/c/sub@other.instance" shows the external community's sidebar, bur not the posts I know exist.

I haven't added anything to the allow or block list and federation is turned on. Have I missed something or is it just a matter of waiting a little more?
