How to download content on save the world

So I downloaded Save The World on Fortnite maybe a week or two ago, but the thing is i only finished what they gave me and when I try to play more is will say content not ready, and that it must be downloaded to continue but it doesn’t show that anything is downloading. What can I do to install the next part please help, I just wanna play Save The World!

I have the same problem…what can I do???

Go to Epic Games Launcher, then Library, point to Fortnite icon, then press three dots, that are right by Launch button, press Settings, then put a marker for Save The World, press Apply/OK and wait until 6GB of STW are downloading.
