Please fix

I love snapchat, its the only app I use to take good pictures on and the main way I communicate with friends. I updated snapchat and now I cant use it, I open the app up and it kicks me off immediately.. I have an iPhone 6s with iOS 10 and Ive never had problems with my snapchat till now.. please help
