ctOS app i cant play with my buddy

I bought watch dogs a couple of days ago and started playing,when i read this article about the ctOS app i though it was a very cool idea and told my friend to download the app and play..i added him in my uplay account but it doesnt even show him online and dont know how to play with him...I read some of the ubisoft announces saying that watch dogs release crippled their servers but im not sure if this is whats stopping me from playing with my friend..also tried the app and i cant even find a quick match! anyone can help me out understand why this is happening and how can i can fix it
