Bug fixes and performance improvements
This feature allows users to enable or disable Exposure Notifications at any time in their phone’s settings. The presence of this feature on the phone does not indicate that Exposure Notifications has been enabled, and Exposure Notifications is not automatically activated. To enable Exposure Notifications, users can go to Settings -> Google -> COVID-19 Exposure Notifications. Exposure Notifications is a voluntary service and users can opt in or out at any time, as well as decide whether to share information through the system to help warn others of possible exposure.
This is the official COVID-19 Exposure Notifications feature of the Ministry of Health of Yucatan, Mexico.
