The app overall is simple, but as other reviewers have stated VERY slow. Additionally, until the last update I hadn't had any problems with my transactions and reward points being updated. Now have five separate but consecutive visit transactions (and the subsequent reward points) not be processed/accounted for. When I go to 'Review Recent Transactions', it tells me I have none. Every time. Frustrating and a bit pointless to utilize this app when it's main function is utterly non-functional!
