As the title suggests I didn't know you shouldn't do that apparently, I used my nnid to make an pnid and now whenever I try and log into the Nintendo account into my nnid it just gives me this error. I've checked the password/email/ID things so much, I know they're correct.
I have no idea if this is the right place to ask for help with this so, sorry if it's not.
now I can't use pokemon bank 💔
and photo for I guess proof (?)
