Issues with Posts
If you didn't transfer your account when changing devices, etc.
The Timeline that appeared on your old account is not designed to appear on your new account. Even if you add your friends again, you cannot display the Timeline posts that they made up to that point.
Note: You can view older posts on your friends’ profiles.
If a friend's new Timeline posts don't appear
Please have that friend check whether their Timeline Share settings for you are set to Included.
