I'm sorry but I don comprehend what is wrong, so I will ask questions based on my best guess:
Your account has not been fully verified yet, because the selfie was not approved, right? This may be the reason for canceling your withdrawal.
Try to provide the selfie exactly the way you were advised, please.
Some casinos process small withdrawals without full verification, or your friend's account was already verified - I do not know.
Regarding the rules or app, sadly, I'm lost in the translation. 🙁
Let me know how the verification goes.
