The default Reporting Interval in the Advertiser tab is ‘Yesterday’. Upon opening the Advertiser tab you will see all metrics for the previous day. To see metrics for a different Reporting Interval, select the desired time frame from the ‘Reporting Interval’. Available options include, ‘Today’, ‘Yesterday’, ‘7 day’, ’30 day’ and ‘Lifetime’. ‘Lifetime’ will display metrics from the start date of the Advertiser or Line, until the current date (with a 3 hour delay).
