Users Duplicated Across Subdomains

[andreemic]

Hey, I'm using Splitbee to track users across website.com (landing page) and app.website.com (webapp).

Here's the flow of one user in which a user ends up being tracked up to 4 times.

1. User comes to website.com (tracked as a new user from real source)
2. User navigates from website.com to app.website.com through a "login" button (tracked as a new user from website.com source)
3. User signs up, sign up event is tracked (tracked as a new user!)
4. splitbee.user.set is called and user goes on to use app.website.com (tracked as a different identified user with email, user id, etc.)

So in one flow a single user gets tracked 4 times!
I want the user to be tracked once and once they log in, turn that anonymous user into the identified one.

My setup:

• React, Next.js
• Next.js proxy
• Runs in parallel with GA
