Second Itunes Account
Bought my wife an iPhone SE a few months ago and am now trying to fix her up with some music via iTunes. The app is already on my PC in my username/password
I sign into the account using my wife's Apple username/password. But as soon as I connect her phone it wants to set it up as a new phone either from scratch or using my stored data. Neither are suitable as the phone is already set up and being used. If I go down the line of setting it up as a new phone will all her information already on the phone be lost?
iPhone 5s, iOS 12
