Azure Device Update result code 606 still results in device rebooting immediately

Hello,

I have been using ADU for many years now, but a feature is still not working. As our devices are working in production, they are not allowed to reboot during working hours, they must stay on, so when an update occurs, the device must wait for the night to reboot. I found result code 606 of swupdate handler file that is supposed to mean "Success but deferred reboot" following this documentation, but the devices are still rebooting immediately after updating.

    Hello @LALANNE Jeremie - CELLENZA ,

    welcome to this moderated Azure community forum.

    Azure Device Update is part of the Azure IoT Hub functionality.

    The Azure IoT Hub gets support for security updates and bug fixes.

    Since this behavior seems different from the expected (and documented) behavior, I recommend created a support ticket.
