   We are investigating an issue affecting some customers who use SMS-based multi-factor authentication (MFA) to access Thomson Reuters products. Impacted users may experience delays or failures receiving authentication codes, which can prevent successful login. Customer Impact: Some customers may be unable to complete MFA authentication and access affected products. Workaround: Alternative authentication methods may be available for some users depending on their account configuration. Next update to follow as soon as additional information is available. Our teams are actively working to mitigate the issue and restore normal service. We will provide additional updates as more information becomes available.
