@michael_soprano  Yes, You need to enable the option of "Use third-party cookies".This setting helps you to ensure the same ECID is shared across multiple domains.

Hi @michael_soprano ,

Yes, if you want one ECID to persist across multiple (sub-)domains via the Web SDK, you must enable third-party cookies.

Thanks,
