I'm looking to renew a Norton subscription by entering a product key. I have done the following: Open Norton. Click on Help > Enter Product Key at the bottom right. Then follow the prompts to enter the new key purchased. When I enter the key, some red text appears above the Product Key box. "Before you can start using your Norton subscription with this new key, we'll need some additional information to register it. Please enroll at norton.com/setup. (-2027)" When I get there, I'm asked to sign in (to my existing account) and when I've done that, I arrive at my dashboard. I can see nothing telling me what the missing additional information is. My account details already have name, address, telephone number and my repeat billing details are already entered. What is Norton looking for, please?
