We recently experienced an issue preventing some users from logging in due to a misconfiguration in our Application to Person campaign, which blocked one-time codes sent via the AT&T network.
Upon identifying the problem, we promptly set up a new campaign and collaborated with our texting provider to expedite its registration. Once the new campaign was registered, we successfully migrated all multi-factor authentication text codes to this new setup, resolving the issue for all AT&T customers and ensuring that users on other carriers would not face similar problems in the future.
We apologize for any inconvenience this may have caused our users and appreciate their understanding as we work to improve our services.
