Hello! I understand that when you enter the MeChat game, it immediately exits or crashes out of the game. Let's see if we can get this sorted for you.

First, could you let me know if this happens every time you try to enter the game? Also, have you noticed if this started happening after a recent update to the game or your iPhone?

In the meantime, here are some things we can try step-by-step on your iPhone running iOS 15.8:

1. Restart the app: Swipe up on the MeChat app from the app switcher to close it completely, then reopen it.

2. Restart your iPhone: Sometimes, a simple reboot helps clear temporary glitches.

3. Check for app updates: Go to the App Store, check if there's an update available for MeChat, and install it.

4. Check your storage space: Ensure your iPhone has enough free storage (at least a few hundred MB) because low space can cause apps to crash.

5. Reinstall the MeChat app: Press and hold the MeChat app icon, tap "Remove App," then reinstall it from the App Store.

6. Check your internet connection: Make sure you have a stable Wi-Fi or cellular connection, as connectivity issues might cause the app to exit unexpectedly.

If you have tried any of these steps already, please let me know which ones, and we can go deeper into more technical troubleshooting, such as verifying app permissions or potential compatibility issues.

Also, sometimes the issue might be on the server side or a known bug with the app version itself. I can quickly check if there have been recent reports of crashes for MeChat for iOS users.

Would you please tell me if you encounter any error messages when the game exits? That details help too.

Looking forward to your reply so we can get you back to enjoying MeChat smoothly!
