Pipdig – That helped a lot, thank you. Found this “https://api.instagram.com/oauth/authorize/?client_id=CLIENTID&redirect_uri=REDIRECT-URI&response_type=code&scope=SCOPE” and I wasn’t sure what scope to use, but replacing the SCOPE with public_content fixed it.
Thanks for the help!
Guess I should have looked better before I posted an error post!
Having the same issue today, only happens when I try to update a page with a new link.
