Hello, My parents both share the same Apple ID for iCloud in order for them to be able to share contacts. They are signed into iMessage, Facetime, etc with their own separate Apple IDs. After upgrading to iOS 9, we've found that if there is a missed call on one of their phones, it also shows up on the other's phone as well and causes a bunch of confusion. I've gone into settings and Handoff is turned off. There is also no option at all for iPhone Cellular calls under Facetime so I don't think that would be an issue either. They've been sharing this Apple ID for iCloud since iOS7 and have never had an issues with the previous 2 OS versions. This just started appearing with iOS 9 for some odd reason. Is there a setting that might have been automatically enabled during the update process that I am just missing? Any help would be appreciated. Thanks in advance. And no, turning on family sharing is not an option as they would not be able to share their contacts.
