My company uses DoorDash group links to facilitate team lunches a few times a week. As such everyone is able to enter their selections and this typically works well for us. However there have been multiple occasions when we have been unable to finalize the order with a message that the desire delivery time is unavailable. I called the restaurant and they confirmed that they were open and accepeting orders through DoorDash. This is an issue on DoorDash side and resulted in a loss of time for our team. We ended up going to a competing company and had no issues submitting our order to the same restaurant.
