I had linked up my google analytics 4 for a week, export daily to bigquery
but when i checked the result in bigquery, the traffic source simply doesn't add up. for example, in bigquery it doesn't appear any 'facebook', as it appeared in google analytics report
which part did i missed out during setup the bigquery linking? does anyone have the same issue?
traffic source in google analytics
traffic source in bigquery
thanks a lot!
