CDomainCS does not work without sharing 3rd-Party local storage information across different browser tabs or if the user enabled special privacy settings within the Browser settings.
Safari Browser and Any: CDomainCS does not work with Safari, since the browser does not share 3rd-Party local storage across different browser tabs. Due to this restriction, the feature can not share the iFrame's local storage across different tabs.
Firefox Browser: If the option “Delete Cookies” is enabled, the feature does not work, since Firefox clears the local storage for every new tab automatically, which prevents saving consents.
iOS browsers and iOS devices: Apple forces all browsers to use their built-in webkit, so CDCS does not work with them.
There is no workaround to circumvent these restrictions since it is a functionality of the browser itself or based on custom privacy settings of a single user to protect his/her personal data.
