What do I do if an app isn't sending or receiving voice messages properly?

Please try the following:

1. Exit the application and log in again.
2. Switch to a different network.
3. Confirm if the app's software is the latest. If not, update it to the latest one to see if the issue persists.
4. Restart your phone.
5. Uninstall and reinstall the app.
6. Back up any important data and restore your phone to factory settings.

If the issue persists, contact the Nothing Support Team for further assistance.
