Auto sign doesn’t work on Nintendo Switch

When I enter the game, the automatic login works correctly, but once my condola disconnects from the internet, and it reconnects, I get an error on the screen that says "Automatic login failed". I close the game and put it back, and the same error, I have to do it again manually. This is somewhat annoying, because when you go out with the console to online places, and then reconnect the console to the internet, you have to manually log in.
