We have noticed today that the dialogue box that appears when you deprovision a Chromebook has changed.
The order of the choice for reasons for deprovisioning a has changed.
The "Same Model Replacement" and "retiring from Fleet" options have switched places on the dialogue.
It would be very easy to accidentally retire a Chromebook, and consequently lose a licence if you do a lot of deprovisioning, and haven't noticed the order change.
