In my online dashboard I have the ability to rename devices to a friendly name. This is helpful if you have similar or cryptic initial device names. Unfortunately, on the services page in the dashboard where I review my product seats used it references the original device names when each product was registered. This makes it very difficult to map the product seat used to the current device name.
Secondly, the dashboard counts multiple logins for current user accounts as an individual seat on the same device. For example, my Android tablet has 2 user accounts, both of which I logged in and installed norton security and logged in with my account. This counts as two seats but only really covers one device. There is no clear norton document telling me if one installed and activated account covers other accounts on a device.
