If you’re like most people, you probably use Instagram to keep track of your favorite brands and products. But if you want to delete collections, there are a few things you need to know. First, Instagram doesn’t allow Collections to be deleted permanently. Instead, they are only deleted when the user deletes all of their posts in that collection. So if you want to delete a collection, make sure all of your posts have been deleted. Second, if you want to delete a collection on Instagram, you need to go into the account settings and select “Delete Collection.” Then select “All Posts.” Finally, select “Delete Collection.”
