Issue Summary: On February 1, 2024 between 12:57 AM PST and 3:52 AM PST, some users in Germany were having trouble receiving two-factor authentication codes via SMS. This was caused by an issue with a service provider and has now been resolved. Users in Germany should no longer be having trouble and may also choose to use an authentication app to receive their 2FA codes instead of SMS. Thank you for being patient with us, we appreciate it.
