To explain the problem I am having let me use airbnb as an example. Here is my user story:
Event 1: View Home Page
Event 2: View Paris
Event 3: Select House
Event 4: Sign-up , email = firstname.lastname@example.org -- Note: according to documentation I would alias here
Event 5: Book House
Now months later the user is travelling again. They have just purchased a new computer so they have no cookie.
Event 6: View Home Page
Event 7: View Rome
Event 8: Select House
Event 9: Log in, email = email@example.com -- Note: according to documentation I would identify here
Event 10: Book House
Here is my question. How do I make sure events 6, 7 and 8 are connected to firstname.lastname@example.org?
