@MaristSion  if it helps you, I was able to update all of my devices and reduce the frustration a bit with this method :    1- If the Ipad is freshly formatted in shared Ipad, send the update iOS command before doing anything else and keep sending the command every 1-2 hours (on my wifi with 8 Ipads it took me around 1h 45 to get the last update) 2- If your Ipad was already used before and isn't new, be sure to send the command "reboot" before sending the update iOS. You can't send the command when a user is logged in and I notice sometimes it still doesn't work when you log off properly. A reboot is better in my tests. 3- The most important for me : be sure to have at least 60% of battery or more OR having the Ipad plugged in the wall before sending the command otherwise nothing happen.   Lastly, I feel like when you send the command update iOS (personal opinion on this), it actually starts the download of the update, but you need to resend the update iOS command in order to say "hey start installing too", when the update is over. I've had many cases when I send the command before leaving office at 16h, coming back at 8h and nothing changed. Then I just repushed the command and everything started to install in less than 10 minutes, like if the command only said "just download it, don't install it".   Hoping it's going to be helpful to someone else ...
