Hi there,
Recently we've observed that the Audience report returns not all data.
for example, a query to the campaign report
response:
"CAMPAIGN_PERFORMANCE_REPORT (Jun 1, 2020-Jun 30, 2020)"
Campaign ID,Impressions
10251593972,5958871
Total,5958871
a query to the Audience report
response:
"AUDIENCE_PERFORMANCE_REPORT (Jun 1, 2020-Jun 30, 2020)"
Campaign ID,Impressions
10251593972,41483

So, the count impressions is different. Campaign report 5958871 vs 1136499 Audience report.
Morethan If dig deeper and add to the query AdgroupID dimension you will see that one of the reasons that data discrepancy is missing some ad groups at all in the audience report.
At first glance, those ad groups don't have any differences from others. Examples such as ad groups 101150581094, 101029514623. These ad groups weren't returned in the audience report.
I've closely read the API documentation and didn't find any reasonable explanation of such behavior.
Please explain why it is happening?
Thanks in advance!
