Ok so i have steam, battlelog and this ubisoft club in my IPhone 5s. All of them work 10/10 except this ubisoft club. Most of the time it just stuck at ubisoft logo. The more weird issue, it does not save the login instance, everything i start i had to login. Another thing, it does not show any friends online, it shows them as for example: online 5 minute ago but they are online if i see them from PC. There are so much work needs to be done here. Best of luck. Thanks.
