I've noticed that when I'm offline I can see surge zones and highlighted areas where rides are in higher demand but when I go online all that info disappears and I'm driving blind in a sense because I don't get to see in real time how and where the busy areas are, causing a significant decrease in my earnings lately..I've uninstalled and reinstalled this app several times and still no change...I have friends who use app as well and they seem to not have any issues with getting real time data.
