User Acquisition SKAdNetwork
The User Acquisition report displays statistics on app install sources obtained from SKAdNetwork, a campaign attribution system on iOS 14.5+ that ensures user privacy. Segmentation and event metrics calculated according to AppMetrica data aren't available in the report.
The report is based on the time when data is received from SKAdNetwork: because of the way this technology works, the data is received 24–48 hours after the first launch.
To set the report period, use the drop-down element . The selected time interval can be grouped by hours, days, weeks, or months.
