how to watch video on nintendo switch

When I went to the google photos and clicked on the movie it wouldn't load. Is it because i used a MP4 file.  For me when I try to sign in it says this page cannot be displayed Battery life isn’t great, lasts 4 hours” If you’re like me and your parents don’t allow to play For hours, this is perfect 
The switch needs a big UI update to add basic features like a web browser or Spotify. And virtual console needs to happen, I’d love to have GameCube games on the go. Also I wish it had more 3rd party titles, Cod and gta on the go would be great  Great review. I’m definitely picking up this little beauty just for Pokémon and Zelda. Not to mention it looks so sleek, and enticing😍
