How do I stop this? Both mine and my wife's phone ring when someone call us at home and we're on wi-fi. We're sharing an Apple ID because we need the shared storage space in the cloud. If we each had our own ID, we'd have to pay for 2 plans and I'd prefer not to. When someone calls her it rings my phone and my Apple Watch. I cannot find where to turn this 'sharing' off or whatever it's doing. Sorry if this is supposed to be easy, but I'm a bit stumped right now.
