I normally have my Mac, iPad, iPhone and watch all show messages, whether sent to my phone number or Apple ID. But sometimes it gets out of control and I just want to shut it all off for a while, especially since my mobile number is my work number and my Apple ID is tied to it. But if I turn off my iPhone, my Mac and iPad still notify me, etc., etc.. It can become a game of whack-a-mole to shut it all off (temporarily) but still enjoy using the devices with some peace. Sometimes I think it's all off and then my iPad will ring from across the house! Or my old iPhone 5 I use to control my Apple TV. Is there a quick and easy way to toggle on/off all messaging across all devices at once?
