How to disable the 'Offload Unused Apps' option in iOS?
This is in the settings app in two places by default:


Offload Unused Apps


You can search settings or just do a spotlight search system wide to go right to the place where this is set. (It’s under General and iPad/iPhone storage)

If you don’t see it there, head over to the 'iTunes &amp; App Store' section of the settings app and scroll the content up to look for the same toggle at the bottom of the page. Tap it to disable the opt in for this setting.
