We’re making three updates to the way admins manage their Google Meet hardware devices: 

First, when you generate an export of your device data, that export will now use all active filters you selected on the Device list page prior to initiating the download. Previously, this action ignored filters and generated data from every device in your entire fleet. 

Second, you can now make bulk updates to your device settings by uploading a modified export of your device data in CSV format with your desired changes. Prior to this change, the only way to make bulk changes to device settings that are managed at the individual device level (as opposed to organizational unit level) was to select up to 50 devices at a time on the Device list page and trigger a bulk action. This change will allow customers with large fleets to save time by cutting down on repeated, manual steps when rolling out changes to hundreds or even thousands of devices.

Important note: We recommend carefully reviewing the Help Center article before using this feature, as there is no automatic way to revert changes. The only way to undo changes is to use the bulk update feature again with an earlier, clean fleet data export file, so be sure to keep one saved. 

Admins must have the requisite Google Meet hardware admin privileges to successfully bulk update devices (Manage devices for most changes, and Manage organizational unit settings when using it to move devices between organizational units). This feature cannot be used to assign calendars at this time.
