Hello, my phone was stolen and I lost access to the Microsoft Authenticator app. I am the Global Administrator of my Microsoft 365 tenant, but I am completely locked out because MFA is required and I cannot access the Entra Admin Center to reset my authentication methods. I need a full MFA reset for my account. Tenant domain: <pii removed> Admin account:<PII REMOVED> Error Code: 500121 Please reset all MFA authentication methods so I can access my tenant again. Thank you.
