Thank you so much for providing this information!
Thanks to the Epic account id you set me, I was able to see that the Nintendo account in question is actually associated to what our team calls a "nameless" account. Let em explain a bit more about what this means.
When you started playing Fortnite on your console for the first time, you were asked if you wanted to create an Epic account. If you chose not to do that, our system automatically created a “nameless” Epic account so that all your progress and saved data could be stored for future games. A “nameless” account is an Epic Games account that doesn't contain a password, first/last name, or email address.
To register and gain access to that “nameless” account, follow the instructions in this article: https://epicgames.helpshift.com/a/epic-accounts/?s=epic-accou...
IMPORTANT: Please use an email that you're not currently using on another Epic Games account.You do not need to use the email address associated with your console account.
Once you promote this account to a fully functioning one, you will be able to remove the Nintendo from it and link it to your main Epic account.
I hope this information was useful. Please do not hesitate to let me know if anything is unclear and I will be happy to provide guidance.
Have a nice day!
