For those who have problems with cooperatives. (Tom Clancy's Ghost Recon: Future Soldier)

Hello everybody. I faced such a problem that when I tried to invite a friend to the game, his status was displayed offline. After reading the topics, I saw that this problem arose not only with us. As a result, I found a solution to this problem on another forum and I hasten to share it with everyone:

It turned out that you need to remove each other from friends in a yuple, then both go into the game. Someone 1st in the game must create a room for the game and find a friend there through a search (the other should not create his own room at this time). When a friend is found send him invitations with some text. And only then the 2nd must accept this invitation and after that it will be possible to call a friend into the game.
I hope I helped someone, I myself suffered for 3 days.
