I have CC Photography and have tried to add the Kuler add-on to photoshop but can't. The extensions menu is greyed out and I can't put file sync on. Is it that this is not available with the Photography account?
I solved this by uninstalling Creative Cloud Desktop using the uninstaller and then re-installing it. I closed an reopened Photoshop and the Extensions menu was visible. I am also now able to sync files.
