Adobe Acrobat Pro 2020 won't show a warning that changes haven't been saved before closing
For example, if you add a comment to a PDF and close Acrobat 2020 Pro, the warning about not saving your work will not appear. This warning was normally displayed on the older version of Pro XI, so it appears in the latest version of DC (both Reader and Pro).
The app version is 2020.005.30381
