I am giving this app zero because it never worked. I have installed, uninstalled, reinstalled more than 30 times, and in all, it never worked. I attempted registering, then I was prompted to input the otp received, meanwhile NO otp was ever sent. Next, I saw "your account has been blocked". Then I uninstalled and reinstalled, same issues.... I attempted reinstalling again yesterday because I changed phone and can no longer use my old Diamond App, quess what?, same issues.
