Oh my! Nintendo really doesn't want you doing it that way. Just like Apple.

Personally I love the physical memory options, and hope they keep making physical cartridges for all major games. Without it, Nintendo has too much ownership of the games, preventing me from enjoy collecting, trading, and selling.

I usually spam my screenshots to Twitter, using the built-in share options, and download them from there. After I post a couple, Twitter usually asks me to verify my account again. It is actually pretty difficult to type in my password on the Switch version of Twitter, because it hides the input characters, and does not store the password. It annoys me to the point of insanity.

Honestly, I don't use Twitter for anything else nowadays.

Not my preferred method. If Nintendo would allow me to send screenshots directly to my email that would make far too much sense!

It is good that Nintendo allows us to do this without having to buy their Nintendo Online account. If they offered a simpler way to send screenshots, I might be more tempted to pay the $20 annual fee.
