User Id implementation
Hello everybody, I implemented the User Id tracking for GA4. I did it properly, I am pretty sure I am collecting it correctly because I can see User Id in Real time report and also in Add Comparison tool.
I have 3 problems about how to exploit User Id in GA4 reports
#Problem 1
I don´t figure how to exploit User Id as user_property or custom dimension in my reports. I tried to do it in the Aquisition report but the User Id column show me (not set) value everywhere. When I add comparison with the Comparision tool it shows me up all User Id numeric value in the column, against the (not set) value of the predifined column...
#Problem 2
I also tried to exploit User Id info in the Hub analysis tool but it also shows me all user id in (not set).
#Problem 3
I ended up thinking that GA4 doesnt allow to exploit User Id in it's own interface so I went through BigQuery. But I turned crazy today when I saw that in Bigquery my user_id field had been populated without any value, it shows me "null" in the table.
Could someone help me, I would just like to be able to create a report with a list of all User Id in a row (dimension) and total events count in columns (metrics). How could I do it?
