We noticed a different behavior with the new Admin UI while configuring the system.
For example, if you go to the "Global Application Settings" page under Configuration and try to click on the left side on the configuration entries/lines (not in the checkbox), you will see that you can disable or enable settings simply by clicking on the text vs ticking the checkbox.
This is a high risk from a validation perspective, one setting got unintentionally unchecked during delta configuration in Prod that caused a deviation and a temporary loss of functionality for us.
Did other customers notice this? I like to see configuration changes better tracked in LMS with a confirmation message before we can Apply Changes. in addition, it would be highly beneficial for validated customers to have audit trail reports on configuration pages that we can run on our own.
