I have a web app that uses Firebase Authentication and I have successfully added Microsoft authentication. However, the login screen currently indicates that Publisher is unverified. So, I have registered as a Partner etc but when I try to add my Partner ID in Azure for Publisher Verification it displays the error message: "The MPN ID you provided (xxxxxxx) does not exist, or you do not have access to it. Please provide a valid MPN ID and try again". How do I troubleshoot what is going wrong?
