How can I fix errors code 102122 on apex when link accounts

Hey @Phonegirl21,

Does your Switch username contain any special characters?

If so, can you try changing your Switch username temporarily to remove special characters before following these steps to try linking the accounts again?

You should be able to change your username again afterwards if that's the case, but if you have special characters in your name it's likely that is preventing the initial link from taking place here.
