I’m having the same issue, did you find out how to solve the problem?

I downloaded a Mountain landscape from Fab and I cant seem to download it to the content browser.

Fixed the issue.

Epic Launcher needed updating. I can now see clearly a FAB Libary Section tab. Newly purchased environment is visible with an option to CREATE PROJECT. created, setup, done
