Hi @jfidala , I am using a custom setting due to the unauthorised setting of piwik cookies, see one of my posts here Piwik sets Cookies without consent stg_ - Privacy - Piwik PRO Community
There is no double tracking etc. The meta data gets lost in our commerce SPA due its loading the sales application. Thats why I asked if there is a Piwik data I can reuse to clear the ref data when its empty vs a known source.
