Hi! I understand that you're experiencing lag on the PolyBuzz app and it's not giving any responses. Let me help you get this sorted out.

To start, let's try some basic troubleshooting steps:

1. Restart the app: Close PolyBuzz completely and then reopen it. Sometimes, this clears temporary glitches.

2. Check your internet connection: Since you're on Android 10 and using WebKit, a slow or unstable network can cause lag and no responses. Try switching between Wi-Fi and mobile data to see if it improves.

3. Clear app cache:
- Go to your phone's Settings.
- Tap Apps or Applications.
- Find and select PolyBuzz.
- Tap Storage.
- Tap Clear Cache (avoid clearing data unless necessary, as it may delete your login info).

4. Update the app: Ensure you have the latest version of PolyBuzz from your app store.

If the issue persists after these, we can try some more advanced steps:

5. Reinstall the app: Uninstall and reinstall PolyBuzz. This often fixes corrupted files causing lag.

6. Check for device storage and memory: Make sure your phone has enough free RAM and storage space, as low resources can slow down apps.

If you want, I can also share some video guides that walk through these steps visually.

Could you please let me know if you’ve already tried any of these or how your current setup is? That way, I can provide more targeted help.

Are you connected on Wi-Fi or mobile data right now?
