Discrepancy between data in Google Analytics Dashboard and website_overview stream

I am having an issue with Google Analytics 4 (GA4) source connector. There is discrepancy between the data shown directly in the GA4 dashboard, and the data that is loaded into Looker Studio from the website_overview stream via BigQuery. Can someone explain this discrepancy and ideally suggest a solution?
Airbyte version: 0.42.0
GA4 Source Connector version: 0.1.3
BigQuery Destination version: 1.2.18
