Creating a new Google account from systemsettings / Online Accounts opens another authentication window just after the account is created.

Found this output in the systemsettings stderr:

ADDITIONAL INFORMATION

Note: my Google account has 2FA. Using the yubikey from the login window was not working, so I switched to the OTP method.

Note 2: The Google login window came up in Japanese because my IP is located in Japan. Is the browser view setting the HTTP language negotiation headers?
