First time I tried to use it today, not realizing that scheduling rides in advance doesn't give you a priority. They might as well take that option away because I was ready to be picked up at my scheduled time and even got two alerts stating my ride was on its way so be ready. I waited outside in the freezing cold for a half hour after the time I was supposed to be picked up. Checked the app and it said "finding available drivers" or something to that effect. Cancelled the ride and uninstalled!
