**Your software**  
My Mautic version is: 2.16.3  
My PHP version is: 7.3.33  
My Database type and version is: MariaDB 10.1

When I go to my website I can see that the MTC\_ID shows me a value, I then sign up on my website entering in name, email address, etc. and using the Mautic API I create this contact also sending the IP address of the user.

However, when I look at this contact under Mautic I see a new MTC\_ID is created and assigned to this new user.

I then log out and log back in using the email address of the new user I created but a different MTC\_ID shows in the cookie.

This used to work before and I was able to track “Page Hits” from my contacts but now I can only see “Page Hits” if I click on the “Anonymous” button and view it by IP address.

Does anyone have an idea of why this isn’t working anymore?

Thank you.
