I'm confused though.
That's because you're not listening.
People, including me, have said specifically that they want to be notified of a missing call with no user interaction required. Finding the phone, picking it up, and clicking buttons is user interaction. Simply put: it should be the phone's responsibility of notifying me of missed calls - it's a fricking phone for God's sake. To put it in tech terms, it should be a push notification, not a pull.
What you currently want doesn't exist.
That's why so many people are complaining.
Submit your feedback to Apple here
I don't know about others, but I have submitted my feedback. So far? Crickets chirping.
Maybe if - and when - Apple finally gets around to implementing the feature, they could make crickets chirping the default notification tone as a nod to the years that this simple request has been ignored.
