Reply To: The issue of duplicate TotalUsers in GA4 Query Explorer

[Brooke]

This isn’t necessarily a glitch in GA4. Rather, it’s due to the way GA4 calculates and presents data based on different dimensions. When you select multiple dimensions, like appVersion and firstUserCampaignId, GA4 provides a count of totalUsers for every unique combination of those dimensions. This means if a user matches multiple combinations, they will be counted multiple times, hence the higher total. When you use just one dimension, the count will be more straightforward as the user matches fewer combinations. So the sum value of totalUsers does vary depending on the parameters you choose.
