Something similar happened over here. A post I made early this morning doesn’t seem to be showing in peoples’ streams. Only when they go to the home community can they see it, I believe.

I’ll try to post again in a day or two and report back on what happens.

I’ve also been seeing issues. My ‘hot’ feed has been moreorless static for about 18 hours or so at this point.

Okay, looks like same issue today.
I tried editing the post, but it didn’t jump any higher in the community’s “active” list.

Will try again tomorrow.

Same. Some lemmy.world communities simply don’t federate activity for days for me.

Seems okay today!

The former ‘problem post’ is sorting properly now, and a new post made today looks like it’s being seen by people in the “active” streams. :D
