So, another way to manage your Stories creation flow, and post at optimal times to maximize engagement. Story drafts will save for seven days before disappearing.'

'Instagram Stories drafts are now available for everyone, globally. We asked Instagram for more info on the Stories drafts roll out and it provided this statement:

By having your drafts within the app, you'll be able to view them as they'll appear to users, while you'll also be able to utilize Instagram's full feature set in your draft creation process, and post on the go via the app. But those tools are not native to IG, and are generally not as convenient within your creation flow. Up till now, all users have been able to save their Stories, by either downloading them to their device, or via some third-party apps. The feature could be particularly handy for social media managers who are looking to post at optimal times - though it is also worth noting that you have kind of been able to save and share stories, in different ways, for some time.
