iOS enterprise apps are asking update prompt even when screen is locked with passcode

Issue description:

In iOS 15+ devices, the enterprise apps ask for update prompt when an update for the app is deployed from MDM even when screen is locked with passcode. The app is running on foreground but the screen is locked in with passcode. Previously, in older iOS versions like iOS 12.0, the enterprise apps will not ask for update prompt when an update is distributed from MDM if screen is locked with passcode(and app running in foreground). Is this an intended behavior or a bug? Kindly help us understand this case.

Steps to reproduce.

  1. Enroll a iOS (15.0+) device in a MDM.
  2. Deploy a enterprise app to device successfully.
  3. Open the app in device and lock the screen.
  4. Make sure the device has passcode for lock
  5. Deploy an update for the same app from the MDM.

Expected Result: The app should be installed automatically.

Actual Result: The app asks for update prompt in device.
