If you have a notification rule for Untracked time for more than 30 minutes and an agent is on a New Ticket exceeding the time set for the notification, the rule will execute a notification with a temporary ticket ID assigned by Tymeshift (not a valid Zendesk ticket ID). This is because for any new ticket, the first 30 minutes is taken as ticket time but once the new ticket is being tracked for more than 30 minutes and not submitted, it will be counted as untracked time and therefore falls into the untracked time rule.
Please note that the entire timesheet will be converted to untracked time if the ticket is not submitted once the agent is tracked in a new activity. This will happen on any new ticket timesheet regarding the time spent on it.
First, it will be tracked as "New ticket", and, if it is not submitted, it will be converted to Untracked time.
