If you go to your History page, you can view all of the posts you have scheduled and published through Hopper HQ in the past, as well as your Favourite posts. 

You can then also “view” that picture or “reschedule” it, instantly loading up the image, its caption and its scheduled post time for you to alter as you see fit.

I'm afraid we have had to remove the option to upload content straight from Instagram, due to browser compatibility issues. We'll keep an eye on this and let you know if we re-add this to our uploader. 

Currently, you are unable to re-gram posts published by other Instagram users, but this is on our roadmap for the future. Let us know if you want to be notified when this feature is released 😊
