"I have an iPhone 14 Pro with iOS 16.4.1, and I still cannot get Focus/Do Not Disturb to actually work. It's turned on, yet every call still comes through. I tried resetting the settings on the phone, but that did nothing. I'm not sure how else to fix this, so as a last resort, I have to actually shut my phone off whenever I do not want to be disturbed and want all calls to go to voicemail, which is highly inconvenient. Anyone have any other suggestions?" --- from discussions.apple.com
