Not pulling the right data vs GA interface ?

[Mehdi BOUJEMAA -PARIS-]

Hello there,

I'm using a scheduled run/report to pull data from several GA3 360 properties. For most of properties, the data pulled is correct and is equivalent to data I can see in the interface. However, for 3 properties, the data pulled is almost always wrong. For example, if a metric is "3698" is the report, it's "4569" in the interface, which is a quite big discrepancy...
The report configuration setup is exactly the same. I really struggle to troubleshoot this.

Has anyone seen this problem before ?

Thanks a lot for your help!!!

Having exactly the same issue, data is right across the majority of reports but when I run specific reports, there is always a large data discrepancy with what's shown in GA4.
