After migrating the system to 16.0.1, unable to click save copy button as it is grayed out on the Schedule Distribution page.
Release: 16.0.1
The required fields are empty
The functionality is working as per design.
The feature is designed in such a way that if you do not fill the mandatory fields i.e. the labels marked with asterisk (*), the DLP application will not enable the save copy button thus blocking the feature.
Once if all the mandatory fields are filled with data the feature is enabled i.e. marked in yellow as per below screenshot
