Alerts are important notifications received by Contacts. They include TaG Overdue, TaG WARNINGs and SOS Alerts. Alerts can be sent by push notification to your App or as email. If you tap into an Alert for a USER this takes you to Alert Details, with further information about the nature of the Alert and other useful information.
SOS Alerts are sent immediately when activated. (See also: What are Notifications?)
TaG Alerts are sent after a Timed Pause following the initial Overdue Notification. (see also: Who gets what notifications and when?)
