You have to actually unlock then in the app but my thing is I did that and they still didn't unlock :( if you find a way please msg me at Alien316. Also you can add me if you need a coop partner too :)
Try logging in and out of UPlay within the Spider-Bot app, then unlock the items right after you log in. That's how I got it to work. It seems like if you stay logged in too long it disconnects without telling you.
Unfortunately I lost the 150000 points from the first time I tried to unlock it so I had to gain it back all over again.
