See screenshot. Example here is [email protected] On lemmy.ml I can see several posts, on lemmy.world, none.
I logged in in both, I joined both, both profiles have enabled NSFW content and language is untouched (so all languages should be displayed).
What is the reason for that and how I get the posts on lemmy.world?
It is probably because the admins are setting an amount of time to stop pulling old data. The one you linked is an old one anyway, you should use [email protected] instead.
