Newer versions have some challenges. Three key challenges, 1. The estimate shown changes drastically once you click book. This gives no insight on wait time. 2. Drivers calling you about the destination.. and not showing up if they don't want to go there 3. The earlier option to set the precise location after searching for an area was easy (the search was the starting point for map location). Now any precise location setting starts with your current position... It's become tough.
