I noticed that when I view this post for example on lemmy.world: https://lemmy.world/post/291005 and on dataterm.digital: https://dataterm.digital/post/54221 that both of them are the same post but with a different number of votes and comments.
I believe this also leads to different sorting of the all feed in these instances. Why is that and can it be fixed? Is it even a bug?
I even saw while having both posts open that on lemmy.world a new comment got added in realtime but not on dataterm.digital
This can vary on what instances each is federated with. The more similar federations are between instances, the more similar the counts will be. Also anything to do with lemmy.ml currently doesent federate well at all
