iCloud contacts sync
Hi everyone, I have two iPhones (one personal and one professional) and other Apple products with the same iCloud account. Because I don't want my personal contacts details to merge with my contacts on my professional phone, I turned off iCloud contact sync on my professional phone and left it on on the other devices. However, I noticed that every time I add a contact to one device it goes on all other devices and my professional phone as well. So for example, I would add a contact on my professional phone and it would be added to my personal phone and vice versa. I want contacts added on my professional phone to only be on this phone and same with my personal phone. Any help?
iPhone 7, iOS 13
