Hi! I understand you're having trouble reaching your friend on the Gather app. Let's work through this together. Could you tell me a bit more about what happens when you try to contact your friend? For example, do you get any error messages, or does the app just not connect? Also, are you trying to use chat, a call, or another feature?

Meanwhile, here are some basic troubleshooting steps we can start with on your Android device using the WebKit browser:

1. Check your internet connection: Ensure you have a stable internet connection, whether via Wi-Fi or mobile data.
2. Refresh the app: Try closing and reopening the Gather app or refresh your browser page.
3. Update the app/browser: Make sure your Gather app or browser is updated to the latest version compatible with Android 10.
4. Clear cache: In your device settings, go to Apps > Gather > Storage > Clear Cache, then try again.
5. Check permissions: Confirm that the app has necessary permissions like access to network and contacts if needed.

If you’ve tried these or if the problem continues, please tell me what you’ve tried so far and any details about what you see on your screen. From there, I can guide you through more specific steps!
