Several managed apps used for work collaboration disappeared from a user-owned iPhone.

Managed apps, deployed via an MDM solution, are tied to the device’s enrollment. Unenrolling from MDM (e.g., removing the profile in Settings > General > VPN & Device Management ) deletes these apps, as they’re organization-controlled.

Option A: Resetting network settings affects connectivity, not apps.

Option C: Releasing from Apple Business Manager requires admin action, not user action.

Option D: Signing out of a personal account doesn’t remove managed apps.
