I got a switch for Christmas and would now like to transfer the credit from my sister's WiiU to my switch. As far as I have entered all passwords but now comes the problem: my sister and I do not have the same date of birth and now the switch says that the credit can't be transferred because of this. I also tried to set the date of birth the same, but you can't change it on the Nintendo Account or the Nintendo Network ID. Do you know how to transfer the credit anyway?
Then I would contact support.
