Hi there! I understand your Trivia Star app is stuck on the gems screen on your Android 10 device using WebKit. I want to help get this sorted for you.

Just to clarify, you mentioned trying to close the program and loading a new app, but is that reinstalling the Trivia Star app itself or trying a different trivia app? Also, do you have a stable internet connection when this happens?

In the meantime, let's try a few focused steps to get the app unstuck:

1. Force Stop the App:
- Go to your device Settings > Apps > Trivia Star.
- Tap "Force Stop" to completely shut the app down.

2. Clear App Cache & Data:
- In the same app info screen, tap "Storage."
- Tap "Clear Cache" first, then "Clear Data."
- This resets temporary data which can fix freezing/loading issues.

3. Restart Your Device:
- Power off your Android device fully, wait 10 seconds, and power back on.

4. Reinstall the App:
- Uninstall Trivia Star completely.
- Restart your device.
- Then reinstall the latest version from the Play Store.

5. Check Network Connection:
- Confirm you're on a strong Wi-Fi or mobile data connection — poor internet can cause loading troubles.

6. Allow App Permissions:
- Make sure Trivia Star has all necessary permissions under Settings > Apps > Trivia Star > Permissions.

If after trying these steps the gems screen remains stuck, let me know. We can look into app version compatibility, check for Android OS limitations, or explore contacting higher support. Meanwhile, if you want, I can also check if there are any known outages or bugs reported for Trivia Star on Android 10 devices.

Does this plan sound good to you? And were you able to do any of these already?
