Hello All 👋,
I have created different custom dimensions in Looker Studio, such as: Country Region (e.g EMEA, APAC etc. based on GA4 country dimension), Custom Channel group( based on GA4 session source and medium).
When I set the above custom dimension for example using my custom region dimension together with the average session duration, It seems that the average session duration is summing up altogether. Also, I have tried to change the average session duration metric into "average" the numbers seem a bit high e.g. for some country regions the average session duration t is set to 7hours.
What are your suggestion when it cames using average session duration with custom dimensions? How can I make sure that the average session duration used with custom dimension is reliable?
Thanks
