Hi there! I see your CHAI app has not been working for over a week, and you've already tried everything to get past the limit. I'd love to help get this sorted out for you. To get started, could you please tell me what specific issue you are seeing? For example, does the app not open at all, get stuck on a certain screen, give a particular error message, or something else? Also, you mentioned a "limit"—can you clarify what kind of limit you mean? This will help me guide you better.

In the meantime, here are some advanced troubleshooting steps we can try beyond the usual:

1. Reinstall the App: If you haven’t recently, uninstall the CHAI app completely, restart your iPhone, and then reinstall it from the App Store. Sometimes leftover data causes issues.

2. Clear Cache and Data: iOS doesn't have a direct cache clearing option like Android, but reinstalling usually clears cache data.

3. Check Permissions: Go to your iPhone Settings > CHAI app, and ensure all necessary permissions (like network access) are granted.

4. Network Reset: Try resetting your network settings in Settings > General > Transfer or Reset iPhone > Reset > Reset Network Settings. This clears out any problematic network configurations but will erase saved Wi-Fi passwords.

5. Login Issues or Account Limits: Sometimes, if the app enforces daily or weekly usage limits, it might block access. If you suspect this, logging out and back in or using a different account could help.

6. Check for iOS Updates: Though you’re on iOS 18.7, make sure you have the latest minor updates installed as they often fix compatibility issues.

7. Airplane Mode Trick: Turn on Airplane Mode, open the app, then turn off Airplane Mode. This sometimes forces the app to reconnect fresh to its servers.

If none of these work, it might be worth checking if there are ongoing server issues or maintenance announcements from CHAI, as sometimes widespread outages cause prolonged problems.

Please let me know your answers about the error details and any steps you've already tried, so I can tailor the guidance specifically for your case. Looking forward to resolving this for you!
