For automatic download, your system must be updated and connected to the internet with automatic downloads enabled, and it must have enough storage to complete the download. You'll need to have your console registered as the active console for downloads for your Nintendo Account by visiting Nintendo eShop on the device you wish to download on at least once. To be able to purchase download games or download demos and free software from Nintendo eShop on the official website, you'll need to have a Nintendo Account which is linked to your Nintendo Switch console.
