The app will begin downloading the legacy version (likely version 17.x or 18.x, depending on availability).
Once finished, the YouTube icon will appear on your home screen.
Tap the icon to open the app.
Pre-Installation Requirements:
Picture-in-Picture (PiP): This is the biggest loss. iOS 12 does not support system-wide PiP for YouTube. If you lock your phone, the audio stops. If you exit the app, the video pauses. You have to stay inside the app to watch.
Modern Comment Previews: The home page doesn't show comment previews or "key moments" in the same way the modern app does, but honestly, this reduces clutter.
Reinstalling: Some users found that deleting and reinstalling the app from the "Purchased" section cleared temporary bugs. Install Youtube Ios 12.5.7
Method 2: Install YouTube via Purchased History (For Returning Users)
Q: Can I install the latest version of YouTube on iOS 12.5.7?
A: It's unlikely that you can install the latest version of YouTube on iOS 12.5.7, as it may not be compatible with your device. The app will begin downloading the legacy version
