I really want to update this app. But it's not the problem. I have my own apple ID, but every time I try to update an app, a popup shows up and another account prompts me to type it's password, which I really don't know. I can't really find a way to log-out this account. I tried looking at the settings > store but only one account shows up: my account. I can't seem to access that account, because that person won't go home in a few months. Please help. Thank you!
