The ability to duplicate posts is not currently available in the new version of Adobe Express, but we will be reintroducing this feature alongside a new, and highly requested feature, the ability to allow for multiple account publishing. With multiple account publishing you can connect not just one Instagram account but multiple ones and the same. This will apply for all available social media channels. We are all really excited to bring you this new enhancement, but it did come with some implications, one of those being how you duplicate content and how you'd share content from one Instagram account to another. You can learn more about the updates to made to Content Scheduler here: Content Scheduler Q&A
In the interim, you can upvote the request here in UserVoice and you will be notified as soon as the feature changes status: Duplicate a social media post
