We're sorry to hear that your post has failed. The good news is that it's an easy fix! ✨
"Not a Business Account" means that you have a Personal Instagram account. This sadly does not work with the direct Instagram API (the link between Hopper HQ and Instagram that allows for scheduling!).
You'll need to convert your account to a Instagram Business or Creator account.
Of course, if you need any further assistance reach out to us directly - we're always happy to help!
