I had turned on the Offload Apps on my iPad. Now I want to turn it off, but the setting switch to do that is not under Settings > General > Usage like it was before. I assume that once you turn it on, it doesn’t turn off? I reinstalled all my apps, so there was not a space issue, but that did not help.
I hope that Apple spends some time at some point soon improving the Settings on iOS, including making sure that the search is more flexible and powerful.
