I see the same posts now, even if the order is not exactly the same. I guess it may be some kind of synchronization issue as the servers are overloaded today.

Searching for the url in lemmy.world, I do not find the original post. I only find this actual post where the link is in the post text.

Moreover, I do not have any issue finding the community from the lemmy.world and subscribe to it but how can I find this specific post from there? If the post is not new or hot, it may be burried under all the more recent posts.
