Cannot set up app – Jacksons Let's Go Rewards Review

I literally just got this app and the area to enter my card number is covered up so I have no idea if it acknowledges the entry of my card number. Absolutely nothing happens once I click the card entry field and have entered my card number, and I have to close the app. I tried uninstalling and reinstalling and it didn't matter. Poor design.
