I'm trying to install the Workfront extension. On the My Exchange page, it says I've aquired the extension, and it says it's installed. My CC Desktop App is set to sync, and says it's up to date. My programs (ps, id, and ai) are up to date. I've tried uninstalling the extension from the my exchange page and re-installing. I've tried restarting the programs and restarting the CC app.
In photoshop and illustrator there's an Extensions sub category in the Windows drop-down menu, but no Workfront extension listed and in InDesign there is not even an Extensions sub category anywhere in the Windows drop-down.
What you're experiencing seems unusual. One suggestion would be to try not just quitting the CC app, but logging out, and then logging back into the CC Cloud Desktop app. It may need a simple refresh of some kind.
