Reels can be featured in Explore and shared to Stories. When you upload a Reel, you can also choose to post it to your Feed. All the Reels you create will also appear in a dedicated section of your profile, similar to IGTV posts.
Do reels automatically post to your feed?
Once your post is ready to upload, you can choose where to share it. It will automatically go to the new Reels gallery/tab that appears on your Instagram profile. You can also share it to your feed for your followers to see when they're scrolling through their feeds.
Why don't my reels show on my feed?
If updating the Instagram app on your phone still doesn't enable Reels, you can try signing out of your account and then signing in back into your account. To log out of your Instagram account, tap on your profile picture from the bottom right corner.
