I am having difficulty logging in to Minecraft for Nintendo Switch every time I want to play the game. 

The game boots as normal and when I try to sign in, I have to choose either to store the data on various devices or on the system and then follow the route of having to input the code to the remote connect site which shows that it has logged in successfully but does not log in on the Nintendo Switch system. 

I do not get an error code, and this happens all the time.  There is no connectivity issues and I do have the full Nintendo Online subscription. 

I cannot find any solution and have already uninstalled and re-installed the game and it is running the latest 19.1 update.  I am able to login on the PC version using the same GamerTag etc. with no issues.  Please advise. Thank you.
