Nitsan:
After several years of using Norton, I ended up with a mix of subscriptions:
Norton Internet Security - Installed on 3 devices
Norton 360 Standard - Installed on 1 device
Are these subscriptions active/installed & running on your devices...at this time?
You can wait till these subs expire and purchase/install Norton 360 Deluxe.
You may reach out to Norton Official Support to see if/how they may add days from Norton Internet Security & Norton 360 Standard subs to a new Norton 360 Deluxe subscription.
Please reach out toNorton Official Support and see what they may manage for you...so, you don't lose remaining days.
I'm wondering if your current subs may be upgraded (and combined) to Norton 360 Deluxe.
