New session while Referrer URL on same domain


I don’t understand how this is possible, as both entry & referrer URL share the same subdomain:

Also, Piwik PRO is installed on the two pages. Page views are regularly detected on both:


The session max duration is set to 12h:

And these options are turned off:

The full referrer URL contains multiple parameters, as it’s a landing page used in Google Ads. The new session that starts on the page “/heyflow/projet” loses all of these and is simply attached to source / medium “direct / direct”:

Thank you!

Hi @Thomas_Anode_FR,

Could you share the account URL and the date when this case happened? I have a theory but I’d like to confirm it first.
