If you created a new Post and and did not select an existing Page, this may be why you are unable to see it. Rest assured, you do not have to recreate your post, as it still saved.
Go ahead and open one of the Pages (or create a new one) where you would like this Post to live. In the navigation bar to your right, select Pages:
Next, expand the Posts bar to see if your new post is there, and press ' Add Post':
Select one or more of the Posts you would like on your Page, then press 'Apply'.
Last press 'Update Page' and now your posts will appear on your page.
If you would like to customize the layout and Page view, navigate to the MyShop: Pages.
