Auto update .... actually I have a couple of issues on this. my prior 7+, my IPP, my Mini4, my ex's 7, etc...
First, iOS will tell you that there are X updates available. You go into the App Store and look and you do. But, if you refresh the Update page, you may have more! And if you look at the list of recently updated, there may be several that did auto update.
WTF?
If I just leave it alone and let iOS with Auto-update on decide when and what to update, the list of updates grows slowly and the list of pending just keeps getting bigger. Doesn't matter what device, they all exhibit this behavior. To make it even better, the behavior is similar but not exact.
Just don't get it. As a result I now check daily. I guess you can call this the
iOS Auto Manual Update.
