last night I was driving a passenger and while I was on the freeway I was getting another ping for an another pick up? does this happen and why? aren't we just supposed to drive one call at a time? ALSO, my app froze a few times and ALSO 2x put me at the wrong address... once on a street nearby and the other time way down the street from where the passenger was waiting... THEN because they had to wait they gave me low stars... sheesh... there should be something that says the low stars are for the app not the driver if the app is the reason for your delay... not cool... I guess they have not ironed out the wrinkles in this app???
