Hi there! I see you’re having trouble purchasing items in the Hill Climb Racing app, and it redirects you back to the menu. I’d love to help you get this sorted out. Could you please share a bit more? For example:

- Are you logged into your app store account properly?
- Is your internet connection stable when trying to make the purchase?
- Have you tried buying items before, or is this the first time it’s happening?
- Are any error messages showing aside from the redirection?

Meanwhile, here’s a straightforward approach to try:

1. Check Internet Connection: Make sure your Android device has a steady internet connection (Wi-Fi or mobile data).

2. Restart the App and Device: Close Hill Climb Racing completely and restart your device. Sometimes this clears temporary glitches.

3. Verify In-App Purchase Settings: Since you’re on Android 10 and using a WebKit browser, please confirm if in-app purchases are enabled and not restricted on your device. Sometimes parental controls or security apps can block purchases.

4. Update the App: If the app isn’t the latest version, update it from the Google Play Store or the official source. Outdated apps can cause purchase problems.

5. Clear Cache and Data of the App:
- Go to Settings > Apps > Hill Climb Racing.
- Tap on Storage.
- Clear cache first, then try again.
- If that doesn't work, try clearing data (note: this may reset app progress unless it is cloud-synced).

6. Check Google Play Payment Methods: Ensure your payment method is valid and working by trying a small purchase or checking in Google Play Store settings.

If after these steps it still redirects you to the menu, it might be a known app issue or transaction problem. Some users reported similar issues linked to transaction declines or server problems. In that case, waiting a few hours and trying again or reinstalling the app might help.

Would you like me to guide you through any of these steps in detail? Also, if you tried some already, please tell me which ones so I don’t repeat and can suggest alternatives.

Are you satisfied with this initial guidance?
