Microsoft account on the switch does not work?

I can't sign in to Minecraft Bedrock on the Switch with my Microsoft account. Why is that?

I'm not so familiar with the switch, but I know the Microsoft acc in Minecraft are very laggy, so maybe try again later

You have to wait in the window… The cell phone says that it was successful and that you can close the window. This does not apply to the switch. You still have to stay on the switch for a few more minutes
