My Mobile Security licence expired and rather than renewing it, I've tried to connect my iPad as "another device" permitted to me under my current licence for Norton 360.
I have been unable to do that.
Is it possible to get the free installation on my iPad or do I simply have to pay for the Mobile version?
How old is your Norton 360 subscription? As in have you just been renewing 360 from about 3 years ago? If so, that version did not support installations on mobile devices.
If you have the latest 360 subscriptions you should be able to install and activate the Norton Mobile Security, NMS, app on your iOS device. What error message do you see when you try to install?
One other thought. What version of iOS is in your iPad. You need to have at least iOS 10 to install Norton.
