Hello, I have I-Phone 6 and can not install Norton360, during download says works on IOS 14+
Hello. That version is no longer available nor supported. If you already had/have it installed it will continue working per this article:

If your phone is an iphone 6 S it supports iOS 14. You should be able to upgrade. Iphone 6 is not eligible to upgrade to iOS 14 per Apple.
