Hi there! I see you're having trouble checking in on the Fly Delta app. I’d be happy to help get this sorted for you. To start, could you share a bit more about what happens when you try to check in? For example, do you get an error message or does the app freeze or not respond at all? Also, are you attempting this within the usual 24-hour check-in window before your flight?

Once I know these details, I can guide you through some steps to resolve it. Meanwhile, here are some common fixes that usually help with check-in issues on an Android device running version 10 with WebKit browser:

1. Update the Fly Delta App: Make sure you have the latest version from the Google Play Store as updates often fix bugs.
2. Restart Your Device: This can clear minor glitches.
3. Clear App Cache and Data: Go to Settings > Apps > Fly Delta > Storage, then tap “Clear Cache” and “Clear Data.” This refreshes the app and removes corrupted files.
4. Check Network Connection: Ensure you’re on a stable Wi-Fi or mobile data connection.
5. Try Logging Out and Back In: This can refresh your session with Delta servers.
6. Check Flight Eligibility: Some flights (especially certain international ones) or ticket types may require airport check-in due to passport or visa verification.

If you’ve already tried these or the problem persists, let me know what steps you’ve taken and any error messages you see. I’ll then guide you through advanced troubleshooting or other options.

Does that sound good so far?
