I am using Apple Configurator 2 in combination with MDM from MacOS Server to erase and prepare a supervized iPhone running iOS 14.2.
I can successfully run erase and prepare the device. My goal is to suppress all setup dialog panes. I can suppress all of them with the sole exception of "Written and spoken languages" which is still shown despite all my efforts. I use the Gui of Apple Configurator 2 to configure the prepare step and have ticket "Don't show any of these steps" box. The device is enrolled, Apple Business Manager is setup and linked with the MDM an everything looks fine.
It seems to me that this should work. Somebody have an idea or has successfully achieved this?
