Topic: Can't link Nintendo Account to Miitomo

I hope this isn't too early since Miitomo just came out, but I can't seem to link my Nintendo Account to this app. I went to link my account but every time I try to link it, it says that the request contains an error every single time. I've tried everything to link my account and this error will still pop up ever time. I wonder how other people did it without this error.

Is there a way to fix this error? I already have another problem on my hands so I hope I will find the answer...

I have a similar issue, I'm trying to link my new Miitomo account to my Nintendo Account, when I try it says "Sign in to Nintendo Account was cancelled (support Code 801-0027-0000)"

Code 801-0027 This error may occur if:
You don't have a Nintendo Account created. (I do , I made it a week ago when I got my 3DS and its linked to my 3ds)

You are using an incorrect sign in or password. ( It signed into my Nintendo account and displayed the Mii icon I made vir my 3DS)

Your browser settings are blocking the sign in process. ( I turned on the option ON that the app asked me to turn on when I first tried to link)
but when I click the (OK) button to proceed with the link to Miitomo it fails saying : Sign in to Nintendo Account was cancelled (support Code 801-0027-0000)

What else do I need to do? help please?
