I've recently begun using GA4 and have a query. I attempted to determine the number of new Korean users who triggered a specific web event within a defined time frame. When I set the period from June 1st to July 23rd, it shows zero users for specific dates (July 12th to July 14th). However, when I change the period to July 12th to July 23rd, the data is no longer zero for any date.
I'm curious about the reason for this data discrepancy based on the selected time frame.
