I just got a new iPhone. I migrated it from my old phone. One of the first things I did was to go into Settings on the phone and rename it from "ATJ iPhone 6s" (the old phone) to "ATJ iPhone 14".
It shows up as "ATJ iPhone 14" on the phone itself, when I connect it to my Mac, and as a Personal Hotspot.
ShutterSnitch Backup still sees it as "iPhone" and created a folder just as "iPhone" for my first backup.
Where do I need to change the name?
