Hi there! I understand you’re having trouble with the Tim Hortons Hockey Challenge app not working on your Android device using the WebKit browser. Let’s figure this out together.

To start, could you tell me a bit more about the problem? For example:
- Are you unable to open the app at all, or does the game just not load or respond inside the app?
- Are you connected to a Wi-Fi or mobile data network?
- Have you noticed any error messages or issues with signing in?
- Have you already tried restarting the app or your device?

In the meantime, here are some steps you can try that often resolve common issues with the Hockey Challenge:

1. Check Internet Connection: Ensure your internet is stable, either Wi-Fi or mobile data. Sometimes, connection interruptions prevent the app from talking to the game servers.

2. Restart the App: Close the Tim Hortons app completely and reopen it. This refresh can clear temporary glitches.

3. Update the App: Visit the Google Play Store and make sure you have the latest version of the Tim Hortons app installed, as older versions may have bugs affecting the challenge.

4. Clear App Cache: Go to Settings > Apps > Tim Hortons > Storage > Clear Cache. This removes temporary files that might cause problems without deleting your app data.

5. Check Permissions: Ensure the app has necessary permissions to access the internet and storage, as these can impact functionality.

6. Allow Opening Links in App: On Android 10, go to Settings, search "Opening Links," find Tim Hortons, and set it to "Open in this app" to make sure links related to the challenge open correctly inside the app.

If those don’t fix it, the issue might be on the server side or related to maintenance, which sometimes happens during the challenge period. If that’s the case, waiting a bit and trying again later could help.

Please try these steps and let me know how it goes or if you have any error messages or unusual behavior you’ve noticed. I’m here to get you back to enjoying the challenge!

Are you satisfied with the direction I’m taking to help?
