I have verified that I am using the same Gmail account that received the registration confirmation. I continue to receive AADSTS50020. Based on Microsoft documentation, could you please verify whether my account has been invited as a guest user and assigned access to the application?

    Microsoft support doesn't support organization internal users directly, this includes guest user.

    Instead, each organization's IT administrator is responsible for managing its users according to its internal protocols. You would have to reach out to the resource tenant who invited you, to confirm it. If they need Microsoft's support, the support request needs to come from their admin user via the Admin Center/Entra portal.
