sometimes cpa networks deny your application when you provide less information than they needed. you can email them immediately after denial or call them to ask why they have rejected your application. if they need something just give them, you will get the approval most of the times. I myself got such kind of experiences in some networks. don't get discouraged.
Exactly. Be prepared when contacting them again. Making a phone call is probably the best way. They do not ask too many tough questions on the phone.
MOst of time publisher don't care instructions and signup as they like . If you asked them to send their ID card they will not send it to you but they will email you continue about approval . Filling up whole correct information make situations easy for approval .
I totally agree with you.You have to make sure in your CPA application that you have enough sources to promote their offer.This is the main reason most people forget to do and their application get rejected immediately.
