Hi there! I understand you're using an iPhone 14 Pro Max and having trouble during video calls on the City Tele Coin app — she can see and hear you, but you can't see or hear her. Is that right?

Before diving into solutions, just to clarify:
- Is the issue happening with a specific person or all video calls?
- Are you connected via Wi-Fi or cellular data?
- Have you recently updated the app or iOS on your phone?

Meanwhile, here are some initial steps to try that often help with these types of video call issues:

1. Check App Permissions:
- Go to Settings > Privacy > Microphone and make sure City Tele Coin has permission.
- Also, check Settings > Privacy > Camera to ensure the app has access.

2. Restart the App and Device:
- Force close the City Tele Coin app (swipe up from bottom and hold, then swipe up the app).
- Restart your iPhone to clear any temporary glitches.

3. Update the App:
- Sometimes bugs affect app functionality. Check the App Store for any City Tele Coin app updates.

4. Network Connection:
- Switch between Wi-Fi and cellular data to rule out network issues.
- You could also try resetting network settings (Settings > General > Reset > Reset Network Settings) but be aware you may need to re-enter Wi-Fi passwords.

5. Reinstall the App:
- If all else fails, uninstall and reinstall City Tele Coin.

One important note: I found that the City Tele Coin iOS app has been reported to be temporarily out of commission for some users due to bugs causing crashes1. So if you've tried the above and it still doesn't work, it could be a temporary server or app issue on their side.

Please try these steps and let me know which ones you've already done, or if the issue persists after trying them. We'll get this sorted out together!

Are you satisfied with this approach so far?
