As we understand, network_id is third party cookie and domain_userid is first party.
So if I visit two different sites using same browser having snowplow implemented, I’ll have two domain_userids and one network_id (even validated this behavior just before creating this topic, it was correct for me).
In any case distinct network_id count should be either less than or equal to distinct domain_userid count.
But from data captured till now, we have network_id count more than domain_userid (approx 2.5 times), we have multi-site environments (2 sites).
Not able to understand what is causing such behavior?
