I found Google Analytics showing different values for New User under Acquisition and New User under New VS Returning User in Behavior. May I know why are they different?
New User under Acquisition is a metric and is the number of first-time users to your site, during the selected date range.
New Visitor under the under New VS Returning,in Audience > Behavior reports is a dimension.
New Users should = the same number in the Audience overview and also the Acquisition reports and as a new visitor in the New VS Returning.
Keep in mind, total Users for the date range, will not be the sum of New Vs Returning Users as a User can be both New and then Returning
eg -at the time of their first visit during the selected date range they were New, then if they returned during that same date range.. they are then also reported as a Returning Visitor.
