Back in 2010 I subscribed to "Norton Internet Security", as it was called then, for my Windows NT system, and my account was associated with my email address email@example.com.
Years later, in 2017, I installed "Norton Password Manager" on my iPad, using another email address, firstname.lastname@example.org.
Unfortunately my attempt to enter the "Norton 360" product key in my xyz.com account results in this message: "The product key you entered is associated with another Norton account".
Also I did not find a way do delete my xyz.com account so that I could then change the email address in my abc.org account to email@example.com.
So is there a way to merge subscriptions from two accounts into one, or to transfer a product key from one account to another ?
