The update for XD version 36 s not showing up in creative cloud app, only 35 is visible. I tried suggested methods of restarting creative cloud app, signing in/out, reinstalling XD, nothing helps.
Kindly move that file on the desktop, sign out from the creative cloud, and log in again to check if you are getting the latest version. If the issue persists, I would recommend contacting your internal IT team who would be able to raise a support case with Adobe to look into this matter.
