Hi there! I understand you're seeing a "No Results Found" message when using the Discovery Search feature in the Cookin app on your WebKit-based Android 10 device. I'd like to help you get that sorted out.

To start, could you tell me a bit more about what you are searching for? Also, have you noticed if this happens with all searches or just specific keywords? That info will help me narrow down the possible causes.

Meanwhile, here are some common troubleshooting steps you can try:

1. Check Your Internet Connection: Sometimes search results fail to load properly with slow or unstable internet. Try connecting to a reliable Wi-Fi or mobile data network.

2. Clear App Cache: On Android 10, go to Settings > Apps > Cookin > Storage > Clear Cache. Clearing the cache can fix issues related to temporary data corruption.

3. Update the App: Ensure you have the latest version of Cookin installed. Updates often fix bugs that cause search errors.

4. Try Broad Search Terms: Sometimes overly specific or uncommon terms return no results. Test with general keywords to see if results appear.

5. Restart Your Device: A quick reboot can resolve temporary glitches affecting app features.

If you've already tried these, please let me know, and we can dive into more advanced checks like account-related issues, server-side problems, or app reinstallation.

Are you satisfied with these initial steps, or would you like me to guide you through them?
