`Hideable` MDM attribute not preventing app hiding

I have come across this Hideable attribute for managed apps, introduced in iOS 18.1, and I've encountered some behavior that seems to contradict the official documentation.

According to Apple's documentation for app.managed.yaml, setting the Hideable key to false under the Attributes section should prevent a user from hiding the app. The documentation explicitly states:

If false, the system prevents the user from hiding the app. It doesn't affect the user's ability to leave it in the App Library, while removing it from the Home Screen.

I have configured this in my app.managed.yaml and successfully applied the profile to my test device via our MDM server. However, I am still able to hide the application from both the Home Screen and the App Library.

Here are the steps I'm taking to hide the app:

  1. Long-press the app icon on Home Screen
  2. Select "Require Touch ID"
  3. Select "Hide and Require Touch ID"
  4. Authenticate using Touch ID
  5. Select "Hide App"

After these steps, the app is no longer visible on the Home Screen or in the App Library, which is contrary to the behavior described in the documentation for when Hideable is set to false.

My question is:

Is this a known issue or a potential bug in iOS 18.1? Or, is there an additional configuration profile or a specific device supervision requirement that I might be missing to enforce this restriction correctly?

Any clarification would be greatly appreciated!

Thank you!
