In fairness, it’s so there’s a log of why the machine was shut down. It’s for the sysadmins in charge rather than Microsoft. In practice, most people just choose “Other” as the reason so it’s fairly useless. I have no idea if there’s a way to turn it off, though.
I ran an iPhone for many years and never updated anything at all. The apps were updated automatically.
Edit: Ah, you’re talking about an iOS update. Forgive my lack of reading comprehension. Apps that have been automatically updated have been known to stop working, however.
Who is using the Google app for iOS…?
