I have been doing a lot of cargo/data delivery missions the last two or three days and often during the flight I will get an "urgent mission update" message on the comms channel usually stating that the reward has risen if I deliver quicker. When I open the message the only options available are back and delete, there is no way to tell whether I have acknowledged the message other than that. So sometimes I wonder if I have missed out on the bonus because of that. What is the correct procedure or is it just as it appears?.
