Hi there! I understand you're having trouble searching for characters on the PolyBuzz app. To help you better, could you let me know if you're seeing any specific error messages when you try to search characters? Also, have you noticed if this happens with certain characters or all characters in general?

In the meantime, here are some initial steps you can try to resolve this issue:

1. Check Internet Connection: Ensure your device is connected to the internet and the connection is stable, as a poor connection might affect search functions.

2. Restart the App: Close the PolyBuzz app completely and then reopen it. Sometimes, refreshing the app can fix minor issues.

3. Update the App: Make sure you have the latest version of PolyBuzz installed, as updates often contain bug fixes.

4. Clear App Cache/Data: On Windows, this might involve clearing browser cache if you're using PolyBuzz through a web browser or reinstalling the app. This can help remove any corrupted data causing the search problem.

5. Search Specificity: Try searching using exact or partial character names to see if it makes a difference.

If none of these help, sometimes characters might be missing from search results because they haven't been approved yet or could be temporarily unavailable due to moderation processes. In certain cases, character listings can be hidden if they violate community guidelines or require content updates.

If you have already tried these steps, please let me know, and I can guide you through more advanced troubleshooting or help check if there are ongoing issues affecting character search on our side.

Are you able to try these and tell me how it goes?
