Instagram: How to Hide a Suggested Post From Your Feed

Users can tell the application why they've hidden the content

After Instagram users reach the end of new content from the accounts they follow on their home feed, the Instagram application will show them suggested posts from users they may be interested in. If you ever come across a suggested post you’re not interested in seeing, you can hide it from your feed. This will also allow you to customize your Instagram experience by telling the application why you’ve hidden the post.
