I was logged out of the buggy iOS Call of Duty app and when I attempted to login again it loads a blank screen with a ghosts mask on it. I have done everything in my power to get it to work again and have come to the conclusion its something on Activisions end. After further research I have seen that people are posting about the problem in the Call of Duty app review in the Apple App Store.
Activision..... A little help would be appreciated!
