I'm assuming you downloaded a few games straight to your switch and you're not physically buying the games / downloading the warframe and it's taking up all your storage like i did it It wasn't immediately clear where to put that tiny (less than a dime) SD card, but I'll help you out if you don't already know that the stand on the back of your Switch hides the card slot, so flip the stand up and slide it like the picture on your switch and make sure it clicks exactly the way you put the game in. This happens with any type of storage on almost any device you use, so make sure you buy it 120-119 drives, at least that's what I have left.
