How to prevent iOS devices from auto approving erroneously

Problem

How can you prevent iOS devices from auto approving without an auto approval policy on the Admin Console. 

Environment

  • Mobile Device Management
  • iOS

Solution

  1. Go to the Admin console 
  2. Select Devices > Mobile and endpoints >Settings > Third party integrations.
  3. Confirm this setting is turned off.
Note: If the setting is not turned off, it causes the sign in process on mobile devices to bypass the policies from the Admin console since these policies are the ones on the third party EMM provider that you setup.  

Cause

Issue is caused by the third party EMM integration policy being active.
