How to schedule Facebook Reels and Stories
Select the Facebook Page. In settings, choose Feed and Reel for the same single video to publish one Page Reel. Add Story to publish a separate Story in the same submission.
Attach media prepared for that destination, write the accompanying copy, and inspect the crop and preview.
Review the available engagement settings, choose a publishing time, and check the published result on your Page.
Keep in mind: To publish a separate Feed post, give Feed its own media.
