Similar to how you can share what you’ve been listening to on Spotify to Instagram Story, you can now share your posts and public posts in your timeline, too. When you share a post on Story, it’ll come up like a sticker and will have the original poster’s username and a link to the original post. It’s an easy way to promote brands or friends to your other followers. If you don’t want other people sharing your content, there is an option in settings you can toggle. Simply scroll down and look for the “Allow Others To Reshare” option. If you have a private account, you don’t have to do anything. The feature is rolling out on Android already. iOS users will be getting the feature in the coming weeks.
