The app freezes, pauses the workday, and the embedded map malfunctions constantly. When the app malfunctions, the driver's rating drops because orders can't be sent to the driver or delivered by the driver. This dropped rating can cause the app to stop sending orders altogether (as a penalty). Dasher help either reads a script of unrelated information or places you on hold midsentence when you're trying to get help with the app or the unfair rating drop. Waste of time!
