Managed to set up an instance using Lemmy-Easy-Deploy but federation is being a bit weird
Is it always weird on new instances, I'm seeing posts from a random amount of days ago, no votes and no comments.
Also, is it possible to federate with communities automatically or do I have to search for them all one at a time to add them to my instance?
It wasn't but now it does I guess. I just searched a community didn't existed locally on my instance and I got same result as you. No votes, no comments. I think this is enough to open an issue in the Lemmy repo.
I remember there was a tool so you can download your lemmy subscriptions then upload it to your new Lemmy instance so in that way it will federate with those you are interested in. I don't exactly remember the name but if I find it will comment back here.
The stickied posts get a bit weird and I've experienced them staying wrong until new ones are set. But this was last summer, unsure if it works better now or not.
The only thing I find concerning is the post "feedback on design and Firewall options" which you don't have and really should have unless there's something odd with that specific post. I have noted some issues with federating content from kbin/mastodon etc users but I saw that post on my self-hosted Lemmy instance...
