You can only create unpublished video Page posts if you're the admin of the Page that you're creating them for.

If you want to create an unpublished video Page post in Ads Manager, bear in mind that it may take up to 15 minutes for the video to process and appear in the list of Page posts below Ads posts.

If you don't see the video Page post appear in the Manage Pages drop-down after 15 minutes:

1. Refresh your browser.
2. Download your ad accounts in Ads Manager again. The video Page post should appear.

If you want to schedule a video Page post to run in the future, you can schedule a Page post directly from your Page. Bear in mind that this post will be live.

Report a problem:

Note: You may encounter an issue with some videos where they don't upload because they have been flagged for copyright issues. In this case, you'll get an email notifying you of the issue and what steps you can take.

If you're a Page admin and still can't create an unpublished video Page post to run as an ad in Ads Manager after following these steps, report a problem. To report a problem, click Help on the top right-hand side of Ads Manager and click Report a problem.
