Issue: 

On supervised iPhone devices, when we send Activation lock Bypass command from console, it will always results in failure and we can see the error message under Device Details -> Delivery Groups. 
Issue is seen only iPhone models and on iPad it works fine. 

We have confirmed Activation lock enabled is set to Yes, and we can see the Activation lock bypass code value on console as well.

Engineering teams are working on this issue and as a workaround, we should use option of entering code generated on CEM console manually till fix is identified by Apple and our engineering teams.
