When logged into the application via a web browser, while sharing you can choose Advanced Scheduling to set a specific publishing date or Add to Queue to leverage our publishing algorithm. For more information about how to share, see How Do I Share Content on the Web?
To manage your scheduled and queued posts, log in via a web browser, click on your profile at the top right-hand corner of the page, choose Profile in the drop-down menu, and then select Share Queue in the left navigation bar. Once you've opened the Share Queue, you will see all of the content that is currently scheduled to be published in the future.
In the Share Queue, you can Edit your scheduled post, click Share Now to publish immediately, or click Delete to remove the post from the publishing queue.
