Troubleshoot Android app issues
Please try the following:
- Clear your app’s cache. You can do this by navigating to Settings > Apps > YouTube (it may be found under the All tab) > Clear data.
- If the issue persists, try uninstalling updates on your YouTube app. Navigate to the Settings > Apps or Application manager (this may differ depending on your device). Tap the YouTube app and select Uninstall updates. If you don't see this option, you may not have any updates to uninstall.
- Upgrade to the latest version of the YouTube app. You can do this in Google Play.
