No idea how I got there but somehow I saw this post somehow on sh.itjust.works, about a prefab house that was found floating in the Pacific. I wanted to comment but the only login I have is on lemmy.world. Notice the post is from The Picard Maneuver, whose posts I've seen many times, and it says lemmy.world above their name.
Lemmy.world has a whitepeopletwitter community but the newest post is 2 months old. This one is from 10 hours ago. Search on the lemmy.world main page for "Minding" turns up a bunch of posts going back months, but this one isn't there.
I thought I understood how federation works but I'm stumped. Is this really a lemmy.world post? If not, what does the presence of "lemmy.world" on it indicate?
I wonder if you're running into the same thing that I've had quite a bit of issue with in the last few weeks on lemmy.world.
When I go to the 'copy' of a post on lemmy.world from another instance, I will get the same message of "You must log in or register to comment."
Only by searching for the post on lemmy.world, clicking through to it, and then also refreshing, does lemmy seem to acknowledge that I am in fact logged in! But only if I do those steps in that order.
EDIT: I've made it a bit easier for myself by setting up the search engine in my browser:
https://lemmy.world/search?q=%25sSo that I can just copy any other instance link, go to the address bar and type
ls(the keyword I chose for the search engine), paste in the link and then go to the lemmy.world version from there, and refresh the page.I used to be able to just use the Instance Assistant for Lemmy & Kbin extension by cynber, but for the last few weeks I have to do the whole search and refresh dance instead.
