Highway is currently monitoring a service-impacting disruption with one of our upstream providers that serves one-time passcode requests. Some Highway users have reported that delivery of one-time passcodes is delayed or failing. This is due to an issue between our upstream provider and the target recipients' service provider. While this issue is not within our control, we are diligently monitoring this incident and will provide subsequent updates as we receive more information. We appreciate your patience.
