but the option to choose a new time was greyed out
Which only ever happened for me if I had already pushed back an update multiple times. Which then means they had all the time in the world to make sure they do the update before they start such a critical, multiple days long process. These are people without forced update they would never make updates and they are the reason forced updates have to happen now.
