When will better support for Instagram existing posts be implemented?

Hi Mark, unfortunately, no solution available yet as Facebook doesn't let us promote an existing Instagram post. We've been exploring some options like duplicating the content of the existing post and recreating it, but that's obviously not as good since you are losing all the organic engagement. We are actively discussing this with Facebook and hopefully, we will get a solution at some point. Currently, the only way to promote an existing Instagram post is through Facebook Ads Manager, or through the Instagram app with a business profile.
