Does Instagram allow scheduled posts?
You can only schedule single photos and videos directly to Instagram. To schedule carousel posts or Instagram Stories, you will need to use notifications. Auto publishing to Instagram is available on all Later plans, and can be done from your desktop or the mobile app. Note: free plans cannot schedule videos.15 Nov 2020
