Stop duplication across devices
Hi All
I have an iPhone 6S.
I bought my wife an SE and used my apple ID to set it up - all good, it works independently.
I bought an SE for each of my children again using my apple ID - if one downloads an app, it appears on the other child's phone. Photos from my phone are appearing on one of the children's phones.
I want all devices to share my apple ID but be independent - i.e. not have to have the same apps or see each others photos.
Can anyone explain please how to arrange the above, ideally without needing to do a factory reset and start again.
