updating 14.0 software
you tube is not download
error is 14.0 update
iPhone 6, iOS 12
Question marked as
You have an iPhone 6. The highest iOS version that can be installed on it is iOS 12.x.x and nothing higher. You will need a newer model iPhone to install iOS 15/16.
The YouTube app requires iOS 14 or higher to download and install. This is the reason it does not work on your iPhone 6.
