Then simply tap the arrow at the bottom of the screen once you are ready to publish.
Instagram Reels also offer the option to include a caption, choose a cover image, add hashtags and publish the resulting video to Reels – for those with a public account.
Reels will appear on Explore and be stored on a tab on users’ profile page, as with IGTV.
Another option is available for both public and private accounts – the ability to post Instagram Reels to your Feed.
These Reels will appear on both the main grid and the Reels tab.
