Brief backstory, followed by statement of problem, followed by question.
Backstory: Our Norton 360 Deluxe Subscription allows protection for up to 5 devices. We currently protect (1) our Windows PC, (2) an iPad Air 4th Gen, (3) 2 iPhones. Total=4 devices. The Norton 360 app is installed on the iPad and on both iPhones.
Backstory cont'd: I also have an annual subscription to Norton Mobile Security that I purchased from the Apple Store. I pay for this subscription IN ADDITION TO what we pay for our Norton 360 Deluxe subscription.
Statement of Problem: My Account Norton.com says we have 5 of 5 licenses used. Detail shows the iPad Air, the Windows PC, an iPhone named with a person's name, and TWO other iphones. Further detail shows that the licenses for the "two other iphones" were installed on 10/6/22 and 10/9/22 respectively. These "two other" are actually the SAME PHONE.
Statement cont'd: I spent a great deal of time on the phone with Norton Customer Support on 10/6/22 correcting the problem of a duplicate listing for iPhones. At that time, we deleted both offending licenses from the dropdown list, somehow re-added one, deleted the Norton 360 app from the phone, and re-installed the app. That seemed to fix the problem. However, the problem has recently re-appeared.
Question: (a) how can we resolve this problem once and for all so that we have a total of 4 licenses used (PC, iPad, iphone named, and ONE other iphone?) (b) Does the in-app Norton 360 subscription cause the duplication, and should I cancel the in-app subscription?
