Messages syncing across different Apple IDs
A few years ago(2016) my dad set up my first apple device which was the iPad Air 2. He set it up with his own Apple ID as he wasn’t sure what else to use. My problem is that now I can see messages sent by him and from other people to him. This is problematic for a number of reasons which I don’t think I have to explain. Anyway, I changed the Apple ID associated with my iPad in settings but I still received his messages and messages sent by him said they were sent by me. Also I am 100% sure that he is using his Apple ID to send and receive messages. I checked my contact card for sending and receiving messages and it had my name and I’m not sure if we are using the same contact card as well.
I would greatly appreciate help in solving this issue and the cause of it. I am open to answer questions if needed.
