Why are some Feed posts not displayed in the block?
Make sure the required posts are not hidden. Check the visibility setting for each post.
Check which Feed section is displayed in the block under block content → display Feed. The missing posts may belong to a different section.
Check the filter by date setting under block settings → main settings. For example, if show when the date arrives is selected, posts with a future publication date will not appear yet.
Go to block settings → main settings → number of visible posts before the load more button. If this field is empty, the block displays 36 posts by default. If the Feed contains more than 36 posts, some of them may not be visible. Enter the required number of posts and save the changes.
You can change the load more button text under block content → More.
