Hi! I understand that when you open the YouTube app on your WebKit device running Android 10, you only see the logo and then nothing loads afterward. Thanks for letting me know you've already tried the usual fixes. Just to clarify, could you tell me which "usual fixes" you've attempted? For example, have you tried restarting your device, clearing the app cache, or reinstalling the app?

Meanwhile, here’s a common step-by-step approach we can try together, which covers from simpler to more advanced fixes:

1. Force stop the app and clear cache:
- Go to your device's Settings > Apps > YouTube.
- Tap Force Stop.
- Tap Storage and then Clear Cache. This won't erase your data but clears temporary files which sometimes cause loading issues.

2. Clear app data (this resets app settings):
- In the same Storage section, tap Clear Data. This will reset the app to its default state, so you may need to log in again.

3. Check for app updates:
- Open the Google Play Store, search for YouTube, and make sure it’s updated to the latest version.

4. Restart your device:
- A fresh reboot can help resolve network or app hiccups.

5. Check your internet connection:
- Make sure your Wi-Fi or mobile data is working smoothly. You can try toggling it off/on or switching networks.

6. Uninstall and reinstall YouTube:
- If the above steps don’t work, uninstall the YouTube app via Google Play Store or device settings, then reinstall it.

Because your issue seems persistent, after trying these, if it still doesn’t load past the logo, it might help to try a network reset or check if there’s a system update available on your Android 10 device.

Let me know what steps you've tried so far, and we can dive deeper if needed! Are you able to perform any of these right now?
