1. Check Internet Connection: Ensure that your device has a stable internet connection. Try switching to a different Wi-Fi network or using mobile data to see if the issue persists.

2. Refresh the App: Close the Talkie app completely and restart it. Sometimes, simply refreshing the app can resolve temporary glitches. If the app is in a web browser, refresh the page.

3. Clear App Cache:

- For iOS: Go to Settings > Talkie and enable any necessary permissions.

7. Reinstall the App: If you are still experiencing issues, uninstall the Talkie app and reinstall it from the app store. This can resolve deeper problems that may not be fixed by other means.
