Hi! I see the sound is unavailable only in the Lemon8 app on your iPhone running iOS 18.5, and you see the message "sound unavailable" at the bottom of the screen. Let's see if we can get this sorted out together.

To start with, can you tell me if other apps on your phone are playing sound normally? Also, have you tried restarting the Lemon8 app or your device yet? Sometimes, a simple reboot can clear minor glitches that affect sound.

Meanwhile, here’s a step-by-step to try:

1. Close the Lemon8 app completely and reopen it.
2. Check your iPhone’s mute switch (on the side) and volume buttons to ensure the sound is not muted or too low.
3. Restart your iPhone to refresh the system.
4. Make sure your Lemon8 app is updated to the latest version available in the App Store.
5. Check your iPhone’s Settings > Privacy > Microphone and make sure Lemon8 has permission to access the microphone.
6. Verify that your location settings are enabled for Lemon8, as audio availability can sometimes be region-specific.
7. See if connecting to a different Wi-Fi or cellular network changes anything, to rule out connectivity restrictions.

If you’ve already tried these steps, let me know so I can help you dive deeper, perhaps looking into any account issues or server-side problems.

Would you like me to guide you through any of these steps?
