I just had N360 auto-updated (Feb-2017), but I now learn the product was discontinued and the pricing is much better for Security Premium. That should have been communicated before they debited my account. In another 30 days my Mobile account is set to renew. Should I replace BOTH N360 and Mobile with Security Premium? Or if I go to Security Premium, do I still need Mobile? What does Mobile offer that Security Premium doesn't?
