Hi Greenix,
Assuming that you are not on GA4, to link Google Analytics to BigQuery you must pay attention to 2 things:
- You must be an administrator of the Google Analytics property (the edit permission is no more valid since few months)
- You must be the owner of the BigQuery project
If you already made the linking but don't have data please check if:
- In the IAM console in the BigQuery project verify if the linking service account analytics-processing-dev@system.gserviceaccount.com have the editor permission
- In the Logging Service, check the BigQuery logs errors you may have about the session tables creation and past it if you can't understand it.
