Hi there! I understand your Trivia Star app screen is stuck on the gem screen, and you’ve already tried shutting down and rebooting your WebKit device with Android 10, but it’s still not working. Let me help you get this sorted out.

Here’s what we can try step-by-step:

1. Force Close the App:
- Go to your device’s Settings > Apps or Apps & notifications > find Trivia Star > tap Force Stop.
- Then reopen the app and see if it progresses past the gem screen.

2. Clear the App Cache:
- Sometimes cached files get corrupted and cause freezing.
- Go to Settings > Apps > Trivia Star > Storage > tap Clear Cache.
- Avoid clearing data right away since that might remove your game progress.

3. Check for App Updates:
- Open the Google Play Store, search Trivia Star, and see if there’s an update available. Updating can fix bugs that cause freezing.

4. Check Your Internet Connection:
- Trivia Star needs a stable internet connection to load content properly. Switch between Wi-Fi and mobile data and try rerunning the app.

5. Reinstall the App:
- If clearing the cache doesn’t work, uninstall Trivia Star and reinstall it from the Play Store. Reinstalling can often fix stuck screens caused by corrupted app files.

6. Device Restart with Fresh Boot:
- Turn off your device completely, wait 30 seconds, then turn it back on. After reboot, don’t open other heavy apps before launching Trivia Star.

If the issue persists after these tries, it might be a known bug the developers are working on; Trivia Star team has acknowledged similar issues previously and is working on fixes2. Meanwhile, some users have found that locking their phone and unlocking it again helped the app continue loading3.

Could you try these steps and let me know what happens? Also, if you can tell me if you’re connected via Wi-Fi or mobile data, that might help me pinpoint the issue better.

Are you satisfied with the solution I provided so far?
