Hi Paul, thanks a lot for your answer,
If we put the collector in the same domain, is that correct that domain_userid and network_userid would become equivalent (not the same value obviously, but let’s say redundant) for events tracked with the Javascript tracker?
We own multiple websites we’d like to track our users across. These days with more browsers blocking 3rd party cookies, is the recommended approach to enable cross domain tracking as documented in https://docs.snowplowanalytics.com/docs/collecting-data/collecting-from-own-applications/javascript-tracker/general-parameters/initializing-a-tracker-2/?
