Why can't Tailwind publish directly to Instagram?
At this time, it is against Instagram’s Terms of Service to automatically post to Instagram, which is why we remind you when it’s time to post and help make the process easier to manage. As an Instagram Developer Partner, we certainly wouldn't want to do anything that could jeopardize your account!
Tools that automatically post to Instagram for you are in violation of their Terms of Service, and accounts using tools that violate their Terms of Service in any way could be penalized. If Instagram’s policy on automatic posting ever changes, we’ll make improvements to our scheduler to reflect that.
