    Now some of the Key Points not mentioned in Nintendo official 'changelog', is they are forcing your console to be linked, as explained below, if you didn't un-link your console before today's big official launch, then tough luck you are stuck now, and also the 'Classic NES' library turns off, if you don't go online at least once every 7 days, and finally of course 'cloud saves' don't work with popular games like 'Splatoon 2', due to Nintendo's fear you could somehow use it to datamine, or cheat in their wonderful games!
    Primary Console:

    • You can have one primary console at a time for your Nintendo Account.
    • The first Nintendo Switch console you use to connect to Nintendo eShop on Nintendo Switch will become your primary console.
    • While using the primary console, any user account on the console can play the downloadable content you have purchased.
    • While using the primary console, you do not need to have an active Internet connection while playing downloadable software.
      • An Internet connection is still required to use online features or games which require a subscription service.

    • You can change which Nintendo Switch console is your primary console but you must first deactivate the current primary console.

    Non-Primary Console:

    • A Nintendo Account can be linked to Nintendo Switch consoles that are not designated as the primary console, however, some functionality differs from when a Nintendo Account is used on a primary console.
    • While using a non-primary console, you can still use the Nintendo Account to access the Nintendo eShop, purchase and download software, and under certain conditions, play your downloadable software.
    • While using a non-primary console, you must have an active Internet connection to play downloadable content.
      • If you lose your Internet connection while playing downloadable content on a non-primary console, your game will pause after a certain amount of time; however, once you connect online again, you will be able to resume from the point you left off.

    • While using a non-primary console, downloadable content can only be started by the user that purchased the content.
    • When using downloadable software on a non-primary console, your game will pause if your Nintendo Account is used to access downloadable software on any other Nintendo Switch console.

    You can read about about the 'official changes' HERE on Nintendo's site, and for those running CFW or devices like SX PRO, its not a problem, since developers had the leaked v6.0.0 in their hands for over a week, both SX OS v1.9 works well on v6.0.0 and of course other CFW's like RajNX and ReiNX.
