How to confirm Configuration Profiles are used successfully



I have an app that doesn't appear to be picking up the Configuration Profiles as I would expect it to:

1) Configuration Profile has custom payload plist uploaded.
2) The Profile is shown with correct settings in the target Mac System Preferences > Profiles.
3) Command line shows the profile is in the Managed Preferences section with the correct values.

defaults read /Library/Managed Preferences/

If the app does not appear to be using the new profile, is this an issue with the app, or the way that MacOS redirects the app to read the plist?

Trying to figure out if I need to contact the company about their app (which will likely say they don't support Configuration Profile in JAMF/MDM), or if I'm doing something else wrong.
