The problem I have is, when we send an email out with UTM codes 4 weeks ago, and then another email today with new UTM codes, the visitor tracking of the referral data attributes the data to the old UTM codes.
I found and assume this is the configuration variable to change to expire that referral cookie setReferralCookieTimeout, however it doesn’t seem to be working. See my tracking code below.
For testing, I have set all cookie variables to 5 seconds.
When we view the real time page, the referrer never changes. When we view the referrers source-medium report, it only detects the first source-medium.
Any ideas on how to fix this?
