Problem Cause

Protected Mode and Protected View interact poorly with content on mounted drives. Citrix is receiving reports from customers that the latest update seems to have set Protected View to on by default.

The planned update for both Adobe Acrobat Pro and Adobe Reader was scheduled on February 9th, 2021, according to the following link:
