My new phone is still linked with my old phone.
i gave my old iPhone to my son. Before doing so I was sure I erased all settings but we are finding our accounts are still linked. my contacts are updated when he updates his, and when he makes changes to Siri my siri changes too. I’ve checked the Apple ID and icloud settings and they are set to my Apple ID so Im not sure what’s happening. We are linked through family sharing but I’m also linked to my other kids and don’t have the same problems.
