I thought if I subscribed to a community on a different instance, all the participation is the same. However, I have just realised that the comments are different on the communities even though they should be shared imo

Example: https://lemmy.world/c/[email protected]/data_type/Post/sort/Active/page/1

https://lemmy.ml/c/unresolvedmysteries

You can see that the same post for each instance has different comments showing. Then, in fact, participation isn’t the same between communities. Is this a bug or correct?
