Hello EJL!
Thank you for your reply but I got 0 merged
0 contacts were merged. Just to explain the situation:
Contact A (identified) : email - name - 134.76.129.67
Contact B (unidentified) : no-email - no-name - 134.76.129.67
I already posted a topic with some screenshots, maybe it can help to better understand the issue: Associate IP to existing users
Thank you
