Wow, I had no idea You can accept or reject missions in C2077...Maybe it isn't 'essential' but I don't really want to accept a mission when I have no idea what it is about.
During the call with Wakako Okada in which she gives the job sinnerman, her audio cuts out at the part where she explains the job. Reloading a save did not fix this
Now, seriously: the mission summary is provided by Wakako in a message that You can read from Messages menu.
WeirdI know that if you accept the call when you're at Megabuilding H8 in Japantown, then you should be able to hear the whole thing.
