I’m subscribed to https://lemmy.world/c/vermont, and when I view it I can usually either see “no posts” or only the most recent post.
But I go to the Lemmy.world URL at https://lemmy.world/c/vermont, instead of viewing through lemm.ee via: https://lemm.ee/c/[email protected]?dataType=Post&page=1&sort=Hot
I can see all posts.
In settings there is a checkbox that is labeled “show read posts.” If that’s not checked, any post you look at while logged in will be hidden after you reload the page. Note that this includes even your own posts!
I suspect you’ve cleared that checkbox.
I have the box checked but i seem to be having a similar issue
