Installing the official YouTube app on iOS 12.5.7 can be tricky because the latest version typically requires iOS 16.0 or later . However, you can still get it working by downloading the last compatible version or using a mobile browser. Option 1: Download via "Purchased" (Best for Older Devices)
Storage: Ensure you have at least 200MB of free space, as older versions still require local storage to install .
"Purchase" (download) YouTube there so it is linked to your account.
