The collaborator’s status is “Permission Lost” when Shared Contacts for Gmail™ can no longer access their Google Contacts. As a result, the revoked collaborator can’t update shared contacts or see any updates made by others.
There are two ways to resolve this issue:

When you open the Shared Contacts for Gmail™ dashboard and see the screen below, it means that your shared contacts are no longer accessible to your collaborators, and you no longer have access to their shared contacts either.
To resolve this issue:
Click “Grant Access to your contacts”. Learn more about it here.
Contact your administrator to do the steps stated in Case 2.
As an admin, there are two ways to resolve the “Permission Lost” collaborator status:
Method 1: Grant app access to all users in the domain



You’ll notice that the app distribution is set to “ON for some.” On the left side of the screen, under “Search Organizational Units,” a dark grey circle indicates that the setting is “OFF” for specific Organizational Units. This means that users in those units have a ‘Permission Lost’ status.

Method 2: Reassign the user to a different organizational unit that is authorized to access Shared Contacts for Gmail™.






You can either:
1. Simply wait for the changes from the Google Admin console side, or
2. Log out the admin account, then log in again to see the changes, or
3. The user should close and then reopen Shared Contacts for Gmail™.
