While some of us got to enjoy the new features of version 2.2.0 some of us didn’t due to sign-in issues and we covered this as best we could and even sought out answers, which we then shared, and now Nintendo have put a fix in place.
A new update for Miitomo is available now for android and iOS devices. Downloading it should rectify any issues you had in the past, but if it doesn’t, be sure to let us know.
