I used the “Defer software update” function so that our users could not upgrade to iOS 26 since it seems to be killing the battery on our phones. However, I wanted to send out iOS 18.7 for security reasons. I was able to send it out via Software Updates but if our users don’t catch the update prompt the first time it is sent to them, they will hit an error, and they can not install it other than going to General > Software Update which we have blocked.

I was wondering if anyone has reached a similar obstacle and was able to find the best way to proceed. Thank you!
