问题
Recently we have linked our Firebase project with BigQuery.
But there are no previous (before linking) events data displayed in BigQuery console. Is there a way to get previous data?
回答1:
Firebase Analytics events will be inserted into BigQuery from the moment you connect the two. There is no way to get the events from before you connected them.
