Lawrence Finch: Did you see the part where coolside wrote, "I don’t want to use this feature, ever."? Then why describe settings that only apply when DND is On?
Note Pooh_go_Stillers' comment, "I recommend to switch to Samsung." Apple engineers, designers and managers take note.
I'm using Sonoma v14.4.1 on a MBP and iOS 17.4.1 on iPhone 15 Pro. I've been an Apple Developer since the Apple II days, and this Do Not Disturb feature and defaults break several GUI principles on both platforms. Especially the principle of Least Surprise.
On the MacBook, System Settings, Focus panel, "Do Not Disturb" says "On" but offers no way to turn it off. You have to notice there's a Crescent Moon icon in the menubar to turn it off. Again on the iPhone, you have to know there's nothing in Settings to turn it off, it's the Crescent Moon icon in the Control Center. Once they know to go there to turn it off, there's no reason to describe Focus Settings.
Also note: When I accidentally turned on DND on my iPhone, it also turned it On on my MacBook! So then I found the iPhone Settings > Focus feature, "Share Across Devices" was switched On. I turned it Off, and then turned off DND on the iPhone, only to find out (of course) DND was still On on my MacBook!
I'm sure there are people who find all this flexibility worth the effort to learn how it works. But when someone says, "I just want to turn it off", then don't send them into Settings!
