I use iOS7 to play clash of clans, but when I try to connect with Facebook. It disconnected and when I tried to connect it. It said that login failed, I try everything that everyone said to fixed this problem.
At last, I must delete it. But It useless. I lost all my data and can't log in.
So, Is I must report this problem to Supercell or they have a way to solve it. If you have, reply this question.
Thank you very much.
