Hello! I understand that you’re having trouble finding the First app in the app store search on your Android device using WebKit browser. To make sure I help you best, could you please clarify:

1. Are you searching for the app in the Google Play Store or some other app store?
2. Are you sure the app is published and available in your region?
3. Have you tried searching by the exact app name or different keywords?
4. Is the issue only with search, or is the app also missing from related sections like your installed apps or “My apps” category?

Once I get these details, I can guide you through steps tailored for your Android WebKit environment. Meanwhile, here are some general tips:

Step 1: Check Region and Availability
- Some apps are only available in specific countries or regions. Make sure your Google Play Store region setting matches where the app is available.

Step 2: Use Exact Name Search
- Try typing the exact app name “First” in the Play Store search bar. Sometimes partial or vague search terms can hide results.

Step 3: Clear Store Cache and Data
- On your Android 10 device, go to Settings > Apps > Google Play Store > Storage > Clear Cache and Clear Data. Then restart the Play Store and search again.

Step 4: Check for Device Compatibility
- Certain apps do not appear in search if your device is not compatible. Check the app’s requirements on the Play Store website via browser.

Step 5: Update Your Play Store App
- Make sure the Play Store app itself is updated, as outdated versions can cause search glitches.

If after these steps the app still doesn't appear, please let me know what you find, and we can proceed with more specific troubleshooting for your setup!
