Hi there! I’m sorry to hear you’re having trouble signing up with Google on PolyBuzz. Let's work through this together.

To start, can you tell me what exactly happens when you try to sign up? Are you receiving any error messages, or does it just seem unresponsive?

In the meantime, here are a few steps we can try to resolve common sign-in issues:

1. Check your Internet Connection: Ensure that your Kindle is connected to the internet. You can try browsing a website to verify that your connection is working.

2. Clear App Cache: Sometimes, clearing the cache of the PolyBuzz app can help. Go to your Kindle's settings, find the PolyBuzz app, and select "Clear Cache" from the storage options.

3. Try a Different Browser or Incognito Mode: If you're using a browser, sometimes switching to incognito mode can help, as it avoids any extensions or cached data that might interfere with logging in.

4. Update the App: Make sure you have the latest version of the PolyBuzz app installed. You can check this in the Google Play Store.

5. Google Account Permissions: Ensure that your Google account is not having any issues on other services. You can visit this Google support page for assistance with third-party connections, which might help clarify anything that needs adjusting.

If you've already tried any of these steps or have more details, please let me know, and we can dig deeper!
