To resolve the issue of not seeing the crown after completing 100 levels in Royal Match, here are some actionable steps you can follow:

1. Verify Level Completion: Confirm that you have indeed completed all levels up to 9903. Sometimes, the app might mark a level as completed even if the tasks were not entirely finished or if you missed a daily task. Re-check the specific levels to ensure all objectives were accomplished.

2. Check for Updates: Occasionally, a newly released update might cause glitches. Ensure your app is fully updated to the latest version available on your platform. Go to your app store (Google Play or Apple App Store), search for Royal Match, and check if there is an update option available.

3. Restart the App: After confirming everything is completed and the app is up to date, close the Royal Match app completely. Reopen the app to see if the crown appears.

4. Wi-Fi Connection: Make sure you have a stable internet connection. Sometimes the crowns are not reflected if there’s a problem with the network. Restart your Wi-Fi or switch to mobile data momentarily to check if this resolves the issue.

5. Clear Cache: If you're on Android, go to Settings > Apps > Royal Match > Storage > Clear Cache. This can resolve any temporary file issues that might prevent the crown from displaying.

6. Contact Support: If the issue persists even after following the above steps, reach out to the Royal Match support team. They can provide specific insights and assistance regarding your account and crown progress. Typically, you can find a support option within the app or via the official Royal Match website.

7. Participate in the Royal League: Crowns are important for ranking in the Royal League. Always check how many crowns you should have by comparing with previous updates or community posts about the game, as this can clarify any discrepancies - learn more.
