When I view the All feed, is it just displaying all posts on the local instance I’m logged in to, or does it display posts from all federated instances?
While I can go to a users profile and view the instance they’re registered on, I can’t seem to figure out how to do the same for communities within the app.
It’s all the instances yours is federated with. Usually you’ll see abc@xyz where abc is the community and xyz the instance.
This is exactly how it works
