Recently, we linked big query with Google Analytics. A data set with lots of tables was created. It is accessible, but we noted that not all dates were carried out.
A table shows:
ga_sessions_(478), it means 478 days from now, counting backwards
It points to middle 2015, but if we enter to Google Analytics, we can see data from 2015, 2014 and earlier.
Now we are using big query to get data from Google Analytics and we can't access to 2014 data that we know does exist.
Why are there limits for the periods? Why are the dataset/tables limited?
