Hello YourHighness,
point 2 is clearly not correct and a ticket has been opened. You will be informed as soon as a reply is given why the download failed.
To the other points:
1) In chapter 13.2 of the user guide (see under help in Device Portal) you will find the description how to roll-out artifacts to multiple devices. Via the same way you will find also the command "configure service mode" with which you can bring all relevant devices to a safe state at once without connecting individually to each and every device.
3) The config files "ctrlX Setup" can be uploaded to a Private Artifact Repository which can be requested and connected to your ctrlX Device Portal Tenant also via the help menu in the ctrlX Device Portal. After that they can be rolled out the same way as apps can be rolled out (see point 1 for rollout to multiple devices).
I hope that helps you for now.
Best regards,
Julian
