Passed the game together for my ps4 console.
We finished the storyline, received awards in ps4, after which the host player became available the guard rank, and the second player receives a message that it is necessary to complete all the story tasks (although, I repeat, they were completed in a cooperative game).
Maybe someone has encountered a problem or knows how to help?
The second player should boot up in solo mode and see where they are. Progress in co-op does count for solo as well, but sometimes you need to open up in solo mode to get it to register.
That was done. Unfortunately, the player has not completed the storyline.
Have they tried playing through a bit? In theory, they should get an option to ‘skip content completed in a different session’ (or something like that).
When we finished training, we gained access to the rank of guard and completed the main story.
