Sharing screenshots and videos not allowed by Nintendo Software

I downloaded the Nintendo Switch app because I wanted to share my screenshots from the Tomodachii Life TD game.

When attempting to share it directly to the app, I got these messages, "Screenshots and videos from this software cannot be posted to social media. Screenshots and videos from this software cannot be sent to a smart device."

It's been a while since the game has been released, yet this is the first Nintendo entry where I'm not allowed to share anything from it at all.

Why would Nintendo prevent players from sharing media related to this game specifically? So far, there's no major spoilers. One of my criticisms for the game is that there's too little content at the base price, so it doesn't make sense to bar wanting to share pictures if they consider it finished at this point.
