@rogierlankhorst & @aahulsebos I have the same problem as above mentioned in Chrome concerning https://minitransat.fr/fr/ and https://minitransat.fr/en/.
In the cookies list (inspector->application) here is what I had:
name value
complianz_consent_status allow
complianz_policy_id 14
complianz_consent_status dismiss
complianz_policy_id 14
I had them twice and what helped was to clean manually the cookies and to reload the page. But we cannot ask users to clean their cookies manually. It should not be possible to create twice the cookies needed for the Complianz.
