We have deployed this functionality in our firebase ecosystem. The events are marked for conversion & we see that setup is working. However, we have noticed that post reconciliation of the events real time events (from Cloud Trigger) vis-a-vis BigQuery - the numbers dont seem to match. We understand the feature itself is in preview - but seems we are missing 1/3 events when it comes to real time triggers.
We have done extensive investigation into the Cloud Function Logs & there are indeed missing ga_session_id's which are logged to bigquery but never hit the cloud function itself.
Did anyone face this issue ?
