Cannot access Document Cloud in Acrobat Reader (macOS)

Hi guys,

Previously I've been able to access my document cloud via the Acrobat Reader app directly. But since some time recently, I could no longer find Document Cloud under the FILES section in the app, which only shows My Computer and Add an Account now.

Please let me know if anyone has encountered the same issue/know how to add it back. Thanks!

macOS Catalina 10.15.7

Adobe Acrobat Reader DC 2020.013.20064
