If you purchased ProTube back in 2016, the IPA might still be on your hard drive. It works beautifully on iOS 10.3.4 but requires jailbreak.

If you have previously "purchased" or downloaded YouTube on your Apple ID (even on a newer device), you may be able to download an older version from your history.

💡 : To install any .ipa file you find online, you will need a tool like Sideloadly or AltStore (though AltStore typically requires iOS 12.2+).
