In preparation for the new Mii creation service for web browsers, Nintendo has announced there will be system maintenance taking place from the end of the Miitomo service until late May 2018.

During system maintenance, players won’t be able to change or edit the Mii that is registered to their Nintendo Account, and changes made to Mii characters for Nintendo Network ID will not be applied to the Mii on Nintendo Account.

You have about 8 more days to edit or change the Mii on your Nintendo Account before the long break!
