On Nintendo Switch console I'm not able to connect to Microsoft Account. I found related issue mentioning connection problem after restart. I can't login from the first game start.

1. Sign in from welcome banner on first start doesn't work
2. Sign in from button on main menu doesn't work

I tried ms remote connection link on both, mobile and PC devices, doesn't work. Sign in after deleting game data doesn't work.

I bought game to play on my existing Realm so no way to connect Microsoft account defeats purpose of the game. Unfortunately Nintendo doesn't refund.
