apple id problem
Hello
I have an iphone 11 from my father, and i made my own apple id soon after i received it.
on the telephone now it writes my new apple id,.
but when i try to download an app, and it asks my apple id password, it does not recognize my password marking that password is incorrect, and when i ask to change it to a new one it shows as my id the one from my father (which is nowhere on my device...) and no matter what i do ( put my id and reset password for it, or change my fathers password) when i try to download, it does the same all the way again and again...( say password is incorrect and when i try to reset password it will pop out with the my fathers id ...)
It is a bit crazy and cannot do something for it...please someone help..
Thank you
