Google GSuite Gatelet
Created an Access Enforcement by Gatelet policy to block users from logging into the Gmail service.
The expectation is the policy blocks only Gmail; however, the policy blocked Google Drive and other apps included in GSuite.
The images below illustrate a Policy set to block 'Gmail' yet when browsing (incognito) directly to Google Drive, the Policy is triggered and action is blocked.
Working as designed, no possible workaround.
