For some traits, I'm seeing that the unique visitor volume in Audience Manager is as low as 50% of the volume that we're seeing in Adobe Analytics. Is that normal or does that seem to low? I know that AAM doesn't accept visitors with 3rd party cookies, so I'm sure the discrepancy varies by industry.
Are there any other reasons besides tagging mistakes and 3rd party cookies as to why there would be a discrepancy?
If we have set up server-side forwarding, and if I can see an event (e.g. prodview) has been tracked in Adobe Analytics but after I created a trait using that event, it has been returning 0 in AAM. What could be the reason of that?
