While we don't currently support scheduling for Instagram Stories, this is a feature we would love to offer in the future.
As a small team with a huge product roadmap, we have to pick features that will deliver instant, reliable value to all Hopper HQ customers. For this reason, we're not currently developing a Instagram Stories feature, but will continue to actively investigate this.
We hope to move this into development soon! If you'd like us to keep you updated, let us know.
