We are facing an issue of the user’s initial utm attributes getting updated whenever they are logged out and perform a new login action.
Example:
User: https://analytics.amplitude.com/mentr-me/project/320896/search/amplitude_id%3D487983985929
initial_referrer: http://instagram.com/
initial_referring_domain: instagram.com
initial_utm_campaign: book-a-call
initial_utm_medium: paid
initial_utm_source: facebook
Event url: Amplitude Event
Later when the user revists the site and logs in to his previous account, the initial utms get updated
initial_referrer: http://instagram.com/
initial_referring_domain: instagram.com
initial_utm_campaign: school-explore
initial_utm_medium: paid
initial_utm_source: facebook
Event url: Amplitude Event
I saw on this post that a backend function can be enabled to prevent these overwrites.
Can we enable the same functionality for our project? i.e. initial utms get set only once in the lifetime of the user and are never overridden on merging of sessions or user profiles?
