iCloud tangled up data when signing into other phone
signed out of my iCloud account that was logged into my second phone that was full of my data so my dad could sign in. And it could sync his stuff so he could use his sign into apple to sign into an app in the phone. Then after we were done I signed him out and erased the phone, but now on his iPhone 13 Pro Max, anytime he says “call mom” to Siri it calls my mom instead of his. Is there a way to untangle our data?
