Has this happened to anyone? Unassigned from an order after pick up

Last night I picked up an order from a Sonic and was driving to the customer’s house to drop it off. It was a long drive, 40 minutes from the restaurant to the customer. I was about 10 minutes away from the customer and everything disappeared from my screen. I pulled over to see if I could get the map back up, but there was nothing there. I contacted support and they said the order had been canceled and I would still be compensated. This morning I noticed I hadn’t received anything from that order, so I contacted support again. They said 2 other drivers had been assigned the same order after me, so only the last driver would actually be compensated because he was the assigned driver at the time the order was canceled.

It made me so confused, how can they just unassign you from an order, especially after pick up? And then you don’t get paid anything for driving almost 40 minutes. 😢
