Assume I have Sitecore website A and an external site B. They use totally different top domains. And both use http protocols.
I added FXM from Site A onto Site B.
Setup a goal C to be triggered when user visits Site B. In Site A, setup if goal C is triggered, display D on the Site A homepage.
My question is that, if user visits Site A and Site B in one browser. Should user see D when he/she refreshes Site A after visiting Site B?
I tested this: D doesn't display. But I am not sure if it's Sitecore doesn't support it or I set it up wrong.
Basically it comes down to if Sitecore can track the same visitor under different domains.(see below)
Couldn't find relevant information in Sitecore documentations, it mostly talk about only on external sites.
Thanks in advance!

I found that the cookie "sc_ext_contact" under Site B domain and "SC_ANALYTICS_GLOBAL_COOKIE" under Site A domain have the same value. So Sitecore can identify the same visitor, it's the goal that is triggered on external site is not being used on Site A?
I also tested that, if goal C is used to define a customization for E to be displayed on Site B. When Site B is visited, E is displayed on Site B.
