Fonts will not sync while in InDesign. From my creative cloud desktop app, it says they are synced, however when I try to sync in Indesign it says unable to sync. It seems all fonts synced through TypeKit are unavailable in InDesign. I've gone to the website and in all preferences to make sure font syncing is enabled.
Things to try:
(1) Restart your computer
(2) Restore your InDesign preferences:
(3) In InDesign's Help menu, Sign Out from your Adobe ID, and sign in again.
