Apple Music App on Windows wont show iTunes Music Library or anything

I just tried the new Music app for Windows, but it’s not displaying my iCloud Music Library. I’ve looked online for solutions, but nothing seems to work. In the app settings, the "Sync Library" option doesn’t appear, even though I’m signed in and have authorized my laptop.

The only music that shows up is what I’ve purchased from my iTunes library. Has anyone else experienced this or found a fix?
