It isn't my internet, it's the sh*ty ubisoft servers fault. The worst is that i really need to connect as hurk into somebody's game, to conquer the last trophy for the platinum!
The patch didn't solve anything at all.
It's all that i have to say, once that nobody didn't have commented the last patch on PS4 (1.03)
Please contact our Ubisoft Support if you're still experiencing issues connecting to co-op: http://support.ubi.com
Thank you.
