WHAT A HASSLE! even we submitted it early and should be on time, i have to do some unintall-install inconvenience! i have alot of work to do other than this, takes up too much of my time! and also the ads are not useful just so u know. always hassle after i updated the app! i cant upload properly because its always lag
