I'm a Driver for DD and the app is absolutely horrible. It takes you to the completely wrong complex 1 mile away, constantly crashes, will reroute you out of nowhere and for no reason, will say you missed an order coming through when you literally just heard it buzz and come through 2 seconds ago. There are a lot of reasons why drivers mess up and the app is that reason. Support is absolutely useless because they blame it on your signal despite always being in the city with 4-5 bars, have no solutions when they acknowledge they see the app messing up, and then they hide tips. It will show you many times half of what you could've made when sending you the offer to take the delivery. When you complete it, you see you actually made double. I'd be furious if I were a customer tipping so much and received my food late because no drivers would take a low offer that wasn't because of DD hiding the true payout.
