I have updated my 720 to cyan last week. After installing whatsapp i have requested for a verification code. But i didn't receive a verification code. I also tried getting verification coed via call it also doesn't work. Every time it shows the error " You have recently requested your code". I am getting the same error for 2 to 3 days. I have tried re installing the app but it doesn't work. I've also tried hard and soft reset. Anyone please help me. Thanks in Advance.
