Great Service But App Horrible

I prefer shopping for food at Kroger over Walmart, but Kroger needs to learn a thing or two from the Walmart grocery shopping app. This app never works. The sign in button is unresponsive, the back button logs me out, and the lists dont sync. I find it very frustrating to use and have given up several times and switched to Walmart grocery pickup.
