Issue
Many Firebase and GA4 users have reported significant discrepancies or missing data in their BigQuery exports, especially when using streaming export.
This appears to be a widespread issue affecting multiple projects and users, and various community posts and bug reports have surfaced since 2024.
Reason
Response from Google：
Unfortunately, we can’t fix the issue at this time and apologize for any inconvenience.
Product Engineer Team Comments: Issues like this are often specific and not part of a wider bug. Each case needs individual troubleshooting, so we recommend checking row limits, missing billing details, and ensuring expected events are exported.
If you have any further questions or need assistance with any other matter, please don’t hesitate to create a new issue on the Issue Tracker. I will now proceed to close this issue.
In summary: This is an isolated case; the pattern and cause could not be identified, so it cannot be fixed.
Solution
I suggest trying to link it to a newly created BigQuery project.
