I had this same problem. I solved it by using the Uninstaller apps in the Adobe folder in 'Utilities' which was located in Applications. The instructions came from this page:
After, I just quit the taskbar app and then re opened it from the Applications folder and it worked.
That is correct answer.
Check for uninstaller file for Indesign under Applications>Utilities> Adobe Installers.
If present double click on InDesign uninstaller file and uninstall InDesign.
Then quit and relaunch Creative Cloud or you may sign out and sign in.
Still listed as Up to date .
