I have had several issues with this app not honoring the advertised cash back . I have checked in at locations with the blue badge and used the credit card on file within the app. I make the purchase within the required time frame, but some how I receive a message that I'm missing proof of purchase. I can't click on the purchases in question within the app to get any details as to why my claim is being declined. I would not recommend this app to any more of my friends or family.
