GA4 to BigQuery streaming export delayed for intraday table

[PROP_MTR_Sup]

We have a GA4 property linked to BigQuery with both Daily and Streaming export enabled.
Our app sends events to GA4 first, and we are seeing delays before those events appear in the table in BigQuery. The delay somtimes could be very long up to hours to days.

BigQuery export type: Daily + Streaming enabled.
Data flow: App → GA4 → BigQuery.
Example delayed action time: 22 Jun 16:45.
Checked again at: 23 Jun 11:00.
Result: event still not found in BigQuery export tables.

The issue you are experiencing is usually caused by checking the wrong table, client-side batching delays, or cloud billing/permission blockages. While Google Analytics 4 (GA4) streaming export is designed to push events to BigQuery within minutes, it operates on a best-effort basis and is highly sensitive to setup parameters.
