It would be also helpful if you could create a separate community for the app.

Thanks for all the links. Does one exist with torrents?

Would love to test it as well.

At least one person has to subscribe to that instance from the instance that you want synced, then it starts federating. Unfortunately, it does not update comments/posts that have been made before this first subscription happened. What you can do is manually trigger a sync - to do this, you need to copy the link of the posts/comments and post them in the search bar of the instance you want to have synced. However, this does not work for replies of comments (because the link is for the thread). I hope this could help you.

Yes, at least one person from sh.itjust.works needs to go to https://sh.itjust.works/c/greece@lemmy.ml and click on subscribe. Then everything starts federating from this moment onwards. If you want to see past posts/comments you need to manually search for them on https://sh.itjust.works. If you want the comment https://lemmy.ml/comment/760707 to be displayed, you need to paste this link (after subscribing) to the search field of sh.itjust.works. However, as I said, it does not federate replies of comments because the link is just for the comment. I guess that is a bug/limitation of lemmy, see https://github.com/LemmyNet/lemmy/issues/2241#issuecomment-1112505474

Very nice, can this be pushed mainstream so it is the default for everybody?

I think it works for replies of comments… you need to copy the link from the federated icon next to the chain icon. That is the correct link that should be posted in the instance you want synced.

post it in the original post ;) this is a crosspost

Same for me with https://lemmy.world/c/finanzenat@feddit.de - it works fine on beehaw, sh.itjust.works, etc.

Now let’s create an ROG Ally community :P
