How do I stop my business chat from appearing on another iPhone?
Previous answer does not take into account that I can keep regular messages separate on my iOS devices and my wife’s devices even though all of our devices are under my Apple ID. So business chat should also be separated the same way. There is no reason that these chats can’t be kept separate by the same process used to keep regular messages from cross populating our devices. I do not wish to use the family share function but will if there is no alternative to keeping business chats only to the device it was originated on.
