Steak 'n Shake review: your new app

we had the old app where we put money on the app and then paid with the app when we purchased something, this evening I went through the drive through and the attendant said the updated app has rewards only, I said what happened to the money my wife and I had on the app, she had $30 and I had $20

Where is the money that was on my old app that I used to pay for food at S&S?
