In order for IGTV posts or Reels to be delivered, these types of content will also need to be shared on your Instagram feed. Unfortunately, Instagram does not currently allow for the direct delivery of IGTV content or Reels.
When creating your IGTV or Reels content, make sure that you are allowing for those posts to also be shared on your feed. The option to do so will be present when you go through the steps to post your IGTV post or Reel.
If you posted your IGTV or Reel content but missed the options below, then there are tools that can be used in order to repost them on your feed. One of these tools is the Repost+ for Instagram app and it can be found here!
If you allow for the option to share your IGTV content and/or Reel on your feed, you can then access the content as a post. To successfully deliver it, simply click on the post for your IGTV or Reel content and copy the URL
Lastly, paste the copied URL for your IGTV/Reel content within the task section of the campaign the post is intended for.
