can not ativate font and missing f in creative cloud

Hi Meiliang5ECC,

is your Creative Cloud Desktop App updated to the latest version?

That aside. Can you log-in via browser to the following address:

https://fonts.adobe.com/my_fonts

Here an example from my account using Firefox on Windows 10:

When logged in it should give you the chance to activate/deactivate fonts with the Adobe Fonts service independently if Adobe Fonts is available in your current CC Desktop App or not. Activated fonts from there should show up immediately with InDesign's Character panel.

If you cannot log-in to this web page:
What kind of subscription to Creative Cloud do you have?

Regards,
Uwe Laubender
