2 of us got a code each and both have a ‘Z’ in them. Haven’t managed to figure out how to redeem it yet.
Tried a 2, S, 5 and 7. Then it locked me out.
Yeah ive just checked Z is greyed out. Could it be a 2 maybe? They grey out the letters that can be mistaken for numbers like I, O and Z
I did do and it still blanked out Z on the code input screen.
I cant remember if mine did now, but make sure you enter the code in the game NOT in nintendo estore (even tho on the receipt it tells you to do this). Full instructions where to enter the code are in the ops link
