I just recently bought Dragon Ball FighterZ for the Nintendo Switch. It comes with two codes for the SSGSS Goku and Vegeta and Super Butoden game.
But upon entering the code on the eshop, it prompts an error "The product associated with that code is not currently available".
I just realized that the game I have bought is the asian/Japan version and my account is set to US.
Is there a way or a workaround that I can do to use the code but still using my US Nintendo Account?
