Devices that were showing nothing suddenly display your organization's name on the lock screen and in Settings, without anyone changing a Policy. That is Google's doing: the default for the enterpriseDisplayNameVisibility setting is now visible, so any Workspace that never configured it inherits the new behavior.
Where the name comes from
It is the enterprise display name of your Managed Google Play organization, fixed when the Android Enterprise account was bound to Applivery.
It cannot be renamed. The only way to change the text would be unbinding the Android Enterprise account and binding it again, which forces you to re-enroll every Device in the fleet. In practice that is not a rename, it is a migration.
Hiding it
What you can do is stop it from being shown. The Policy exposes the enterprise name visibility setting, which maps to Android's enterpriseDisplayNameVisibility:
Value | Effect |
|---|---|
| The organization name is shown on the Device. This is now Google's default. |
| The organization name is not shown. |

Set it to hidden in the Policy, and it applies on the Device's next sync. There is no reset, no re-enrollment, and no user interaction involved.
