Shared iPhone Identity
My iPhone and my wife's are somehow linked via Apple IDs and I cannot seem to separate them. When I change her to another Apple ID, it changes mine also. In Family Sharing it treats us like we were one phone. I tried to sign her in with a new Apple ID and it signed my own phone in with that ID also. Any thoughts on how to separate us (the phones that is!) would be gratefully received.
I have an iPhone 13, she has an iPhone 8.
Thank you
iPhone 13
