Various Bloggers report that their new posts, being Published, do not actually show up in the blog promptly.
The usual advice to clear or refresh cache doesn't seem to be consistently useful, though that's still a good place to start. Also, please note whether the missing posts show up in the post editor menu.
>> (Update 8/15): One Blogger reports relief from this problem by forcing a republish of the blog. This was achieved by changing to a different template, and then changing again, to return to the original template.
