Hi there! I’m Frank Taylor. I understand you're having trouble with the IHOP app not scanning your receipt and also not allowing you to manually type in the receipt number. Let’s work through this together.

First, can you tell me if you’ve tried any steps already? For example, did you check your internet connection or try restarting the app? Knowing this helps me avoid repeating what you’ve done.

Assuming you haven't yet, here’s a simple step-by-step plan to try:

1. Check Internet Connection: Confirm you have a stable internet connection since the app requires it to validate receipts.
2. Restart the App: Close it completely and open it again to refresh the session.
3. Clear App Cache: On your Android device (version 10), go to Settings > Apps > IHOP > Storage > Clear Cache. This often resolves temporary glitches.
4. Update the App: Ensure you have the latest version from the Google Play Store. An outdated app can cause scanning or input problems.
5. Try Manual Input Again: Make sure you’re entering the full 13-digit number accurately without extra spaces or characters.
6. Uninstall and Reinstall: If none of the above work, try uninstalling and reinstalling the app. This can fix corrupted files.

If you’ve already done these and the issue persists, it might be related to either a bug or server-side validation errors. The app sometimes shows errors if the receipt code has already been used or if there’s a temporary backend issue.

In that case, I recommend contacting IHOP guest relations directly at [email protected] for account-specific help.

Would you like me to help you step through any of these steps now? Also, let me know what you’ve tried so far!
