This is one of the most poorly made apps I've ever used. If they didn't have app exclusive deals I would never bother using this. It breaks constantly, redirects you to weird pages seemingly st random, and sometimes you just cant finalize your order for no reason. Please fix this garbage Update: app has since signed me out for no reason, now I get a Json error anytime I try to login. If I continue as a guest then I can't interact with anything on the payment screen.
