Hi,
I need to calculate DAU, WAU, and MAU for our app and add these metrics to our corporate dashboard. To do this, I gathered data from App Sessions using the App Store Connect API.
A few days after requesting the reports, they were generated, and I was able to download them.
However, I noticed an issue: the data in the reports doesn't match across different granularities. The sum of sessions, unique devices, and total session duration varies across reports.
For example: sum of Total Session Duration is 52626 for DAILY report, 84553 for WEKLY and 155894 for MONTHLY
Is this expected behavior?
I’m struggling to understand why this inconsistency occurs.
