Hi there! I’m Benjamin Carter, here to help you out with that Popeyes app issue. It sounds like you’re trying to redeem a rewards code from your receipt from store PLK #14632, but the app’s showing “Invalid reward code.” I’d like to help you get that sorted.

First, just to clarify a couple of things:
- Did you enter the code exactly as it appears on the receipt? Sometimes characters can be tricky (like O vs. 0 or I vs. 1).
- Is the code still within the valid date range? Often rewards codes expire pretty quickly.
- Are you logged into the Popeyes app with the same account you want the rewards applied to?

Once I have a bit more info on those, here’s a step-by-step that usually helps:

1. Double-check the code entry for typos or confusing characters.
2. Restart the Popeyes app and try entering the code again.
3. Check your internet connection, since sometimes the app needs to validate the code online.
4. Make sure the app is updated to the latest version available for your Mac’s OS X 10.15.7.
5. If it’s still not working, try logging out of your Popeyes account in the app and then logging back in before entering the code.

If you’ve done all that already, or if you want me to check something deeper, just let me know. I’m here to help!
