Apple Care One is a nightmare. I haven’t heard anybody that has had a smooth experience and nobody at Apple appears to know what is covered nor how to file replacement claims.
I had two reps tell me my Magic Keyboard wasn’t covered as part of my iPad’s coverage.
That’s wrong as per Apple’s own legalese.
Eventually found a “senior support advisor” that is now helping but that’s after 4 transfers and 40 minutes on hold.
Embarrassing.
