Hi there! I see you’re encountering an error message while using the Sun Country Airlines app on your Android device. Could you please share the exact error message you’re seeing? It will help me narrow down the cause and guide you better.

Meanwhile, I can offer some general steps that typically resolve app errors:

1. Restart the app: Close the Sun Country app completely and reopen it.
2. Check for updates: Go to Google Play Store and ensure the app is updated to the latest version.
3. Clear cache and data:
- Go to your device Settings > Apps > Sun Country Airlines > Storage.
- Tap “Clear Cache” first, and if issues persist, tap “Clear Data” (this will reset the app, so you might have to sign in again).
4. Restart your device: Sometimes a quick reboot resolves app glitches.
5. Check your internet connection: Make sure you have a stable Wi-Fi or mobile data connection.
6. Reinstall the app: Uninstall Sun Country Airlines app and reinstall it from the Google Play Store.

If these don’t resolve the issue or if you see a specific error code/message, please share that and I can provide more targeted troubleshooting. Also, are you encountering this error when trying to book, check in, or at some other step?

Looking forward to your details!

Error message system security will not allow

Thanks for the extra detail! The error message "system security will not allow" usually points toward an issue with your device's security settings or permissions that are preventing the app from functioning properly.

Let’s try these steps tailored for your Android 10 device to resolve this:

1. Check App Permissions:
- Go to Settings > Apps > Sun Country Airlines.
- Tap on "Permissions."
- Ensure the app has permission to access things like storage, location, or any other requested permissions.

2. Disable VPN or Security Apps Temporarily:
- If you have any VPN or security apps running, sometimes they can block app functionality.
- Temporarily disable them and try again.

3. Check Device Security Settings:
- Sometimes enhanced security settings, like device administrator restrictions or encryption apps, can block app access.
- Go to Settings > Security and look for any restrictions or enabled device administrators.
- Disable any that might be interfering, but only if you’re confident they aren’t essential for your device's safety.

4. Check for Unknown Sources Settings:
- Some security settings prevent apps from unknown sources.
- Since Sun Country Airlines app should be from Google Play, make sure your device is not restricting apps from Play Store.
- Settings > Security > Install Unknown Apps > ensure nothing suspicious is blocking the app.

5. Clear Cache and Data for the App:
- As I mentioned earlier, clearing cache and data can refresh app settings.

6. Update Your Android OS:
- Sometimes outdated OS versions cause compatibility issues.
- Go to Settings > System > Software update, and make sure your Android 10 is up to date.

7. Reinstall the App:
- As a last resort, uninstall and reinstall the app to clear any corrupted files.

If after trying these steps you still see the error, there might be a deeper device security policy (especially if it’s a work-managed phone) blocking the app from running fully. In that case, do you happen to use a device managed by your workplace or with extra security profiles?

Let me know how it goes! Are you comfortable trying these steps now?
