●Update: Nintendo Account linking issue with password input applications has been fixed in Version 1.0.6 [Tuesday, February 18 at 1:30 pm (JST)]

Version 1.0.6 of Pokémon HOME has now been released. The "Failure to link" problem that occurred when linking a Nintendo Account to the smartphone application, if you have your passwords saved in a password memory application or software (or facial/fingerprint recognition) and try to login to your Nintendo Account, can now be fixed by updating to the most recent application version.
If you have trouble linking to your Nintendo Account, please try updating to the most recent version of the application, and see if it works.
