I could not return my facebook account on iphone

Hi guys.
I have a 33 rd level account linked by facebook. My friend logged out from my account by the ``logout button`` and he logged in with his Facebook account. Now I could not return my account. I am using iPhone 7+. When I log out from my friends' facebook account and click `` Sign in with facebook`` my friend account coming. Only continue and cancel the option available. Please help me, I want to enter my own account. I deleted the game and install it again but this problem still remaining.

First log out of your friend FB account.

Then, login with your FB account.
Then, try T11, as you can not enter with your FB if the FB app have actually open your friends account.

even better delete the fb app while doing this (maybe it has some cookies) and download it afterwards .
