Running AE CC2015.3 and Win10 Anniv.
I was using TypeKit fonts yesterday in an AE project just fine. I open the project this morning and AE says those fonts are missing. I restarted my machine; same problem.
I then launched Illustrator to get to the TypeKit manager website. Then I removed and re-synced the fonts through the website. And now the fonts appear correctly in AE.
So any ideas what caused this problem?
This is Ben from Typekit Support. We've heard a couple reports of fonts becoming unsynced. Resyncing or signing out/back into the Creative Cloud app seems to fix the issue.
