The app, once the order was placed, took over the home screen of my phone, and would not allow me to change apps without difficulty. After the order failed to be delivered, it said the driver sent a photo, but I was unable to open it- I did see the driver park on the street near the house and drive away after I got the alert. I tried restarting the phone, but could not view the photo. The driver did not answer when I tried to call. The app did allow me to get a refund at least.
