Why is there a discrepancy between GA4 interface data and Looker studio data?

[jsimpson1]

Hi there,

I noticed that there is a discrepancy between my GA4 interface data and Looker Studio data, seems a bit strange considering I'm using the GA4 connector in Looker. If anyone could please let me know why this would be great.

In addition to this when I blend two separate GA4 data sources in Looker I also notice that there is a discrepancy with the more GA4 data sources I add. Has anyone else experienced this?

Cheers,

Josh
