Login with facebook shows other ID
This is happening to my sister. First of all I used to share Apple ID with my sister but now I have my own. What's happening now is when she login an app with Facebook ID it shows her picture but the name below is mine. I have never used her phone since this one is her new one, so, I wonder if this is about when I used to share ID with her and I might do something that bind her Apple ID with some of my information, or something like that. Do you know how to make that Apple ID become normal.
