I've downloaded it today on my iPhone4 and it said it would send me a verification 3 digit code before i can use it. Still haven't received it...Has anyone else had a problem like this?
It's because you're now considered a potential rioter thus the Government have blocked your account to prevent the like of what happened last week, cus after all messenger apps are the sole cause of public unrest.
Just delete it and re-download it again and sign up for a new account.
