What if it’s not a option to get the iOS 14

Hello,

There are different ways to ensure the highest iOS/iPadOS that your device will support is installed on your device.

This support article has instructions about updating an iPhone or iPad wirelessly --> Update your iPhone or iPad - Apple Support

You can also use Mac and PC computers to update system software, as outlined in this support article --> Update iPadOS - Apple Support

Use this support article to identify your iPad model --> Identify your iPad model - Apple Support and then the list below to find out what your iPad is capable of running. Alternatively—and somewhat easier—is to simply try updating it and see if it will update. When updating, your device will update to the highest version currently available that it will support, or it will just say it is up to date (and can't go any higher) and won't install anything. If you want to run a higher system version than your current device will run, you need to buy a newer device.

Here's a list of iPad models and the iOS/iPadOS versions they are capable of running:

-iPad Air1, iPad mini2 and iPad mini3 will only update to iOS 12.5.7

What about it?

If your iPad is still running, iOS 12, its likely a model that is not compatible with iOS 13 or later.

If you are trying to download an App that requires a newer iOS version than your iPad can run, then you simply won't be able to download and install that app.
