The system might prompt the [The transfer code you entered is invalid] message when:
1/ You have entered the wrong transfer code.
⇨ As the system is case-sensitive, kindly recheck the characters of your transfer code.
2/ You have already logged in to the corresponding account.
⇨ If the system did not lead you to the profile you wish to switch to, we suggest checking the [Profile] list in your game account. Click HERE to learn more about the [Switch Profile] function.
