New Font Won't Show Up in Harmony

So everything I’ve read up to this point says that if I install a font on my computer, regardless of if it’s TTF or OTF, it should be available in the font menu in ToonBoom Harmony. This is not happening. The fonts are installed, I’ve restarted multiple times, and they are still not available to use.

What else should I be trying to make sure Harmony acknowledges those fonts? Is there a way to tell if a font that’s installed will be usable or not in Toonboom Harmony?

I’m using ToonBoom Harmony 20 Premium.

FIXED: If you’re having the same issue, go back to your font files, and make sure you click “INSTALL FOR ALL USERS”. That should fix it and allow the fonts to work the next time you open a Harmony file.
