I've been happy with this app since August 2021, and it's worked 95% of the time. As soon as the gas prices jumped, it stopped working for me... I mean STOPPED. NONE of my purchases have been credited since early March, and I submit receipts daily as I drive for a living. I even opened a new account, thinking my account fell into some black hole but still no payments. I've contacted customer service twice through the app but no response. Very disappointed.
