Zynga poker app loaded my niece's profile not mine
I play Zynga poker on my iPhone. Last week, it logged me out. When I went to log in using my Facebook profile, it automatically loaded my niece's poker profile. I can log out, but when I go to log back in, it doesn't give me the option to change to my profile. I have deleted the app and reloaded. It always automatically loads her poker profile. How do I get my poker profile back on my phone?
iPhone 8, iOS 12
