When scrolling through Lemmy, I often will see the same posts from the previous page - usually as the first links on the current page I’m on.
Just speculating but, as new posts are made, it pushes the other posts up some, which can make them show up again when you hit next (or hit the infinite scrolling reload point).
I think when a new post is posted and it hits the front page it bumps all the other posts back by that many, which will make them get bumped from the end of one page into the beginning of the next
Next page loads about 3 extra posts for me it seems.
Because new content got posted while you were browsing trough the page. If you refresh the page you’re on it shows different entries on the top and the bottom ones are pushed to 2nd page.
when you start seeing the same posts again and again the deeper you go, that’s your cue to start back on page 1 again.
New posts added since your last refresh push some of current page posts to the next one
You have your answer from every commenter here but this is why it’s best to browse with an app that marks as read and hides stuff as you scroll.
The easiest solution might be to just look at what is returned and see if there are any duplicates with what you already have, and just filter those out. It’s not like you’re going to notice if the returned list is shorter if it loads more before you even get to the bottom.
If you get less than 1 screen of posts, ask for more.
