Hi there! I understand that you're having trouble chatting in the PolyBuzz app on your Mac with OS X 10.15.7. To help you better, could you please tell me a bit more about what happens when you try to chat? For example, do you see any error messages, or does the chat just not respond at all?

Meanwhile, let's walk through some initial steps to try and get your chat working:

1. Check Your Internet Connection: Ensure your Mac is connected to a stable internet connection, as the app requires this to function properly.

2. Restart the App: Quit the PolyBuzz app completely and then reopen it. Sometimes a simple restart can clear minor glitches.

3. Update the App: Check if there is an update available for PolyBuzz in the Mac App Store. Using the latest version can help avoid known bugs.

4. Clear Cache or Temporary Data: Although clearing cache is more common on mobile, if you use a web version or a desktop client, try refreshing or logging out and back in.

If these steps don't resolve the issue, the problem might be related to server maintenance or bugs on their side, as some users have reported similar issues during server fixes1 5.

Could you please try these and let me know what happens? Also, if you notice any error messages or unusual behavior, sharing those details would be very helpful.

Are you currently able to access other parts of the app, or is the chat the only feature not working?
