Could this issue be related to privacy protection? https://developer.apple.com/documentation/analytics-reports/privacy

Hi Romulo, 1-) I am comparing apples to apples. For instance, first-time downloads via app referrer for US is significantly lower than what I see from the web dashboard. 2-) Is this privacy threshold row-based? Because if so, the report has a lot of dimensions which causes the data to be brought down to 1-2 counts for each row. What size should be considered enough to escape privacy thresholds? Is 5k downloads a day enough? Thanks again.

Romulo was right. I was not comparing apples to apples. :( Solved, thanks a lot!
