IOS 9.3.5 doesn't have an update
For some reason my IOS 9.3.5 doesn't have an update. Whenever I click on "software update" it says it's up to date. But when I click on a certain app it says that I need to update to "IOS 12.4 or later". What do I do? Is there someway I can update my pad even if my system shows that there isn't an update to be made?
