We recently upgraded to to two iPhone 6s models. I migrated the profiles from the old phones, and for the first time turned on iCloud Keychain. Both phones log into iCloud using the same account, and both have another account for Messages and FaceTime. After a few days we experienced that the "Recents Calls" list on my iPhone was "shared" to the other iPhone. I instantly checked the ohone settings and turned off "Calls on Other Devices", on both phones, as well as tuned off iCloud Keychain, but alas. The "Recents Calls" list is still shared??? It isn't like a big deal, we have now had this for almost two months, but I would like to figure a way for this synchronization not to happen... Anyone?
