I used the "invite friends" in the email with the alpha key, that will direct you to your friends list and also shows which friend is already invited and which friend you can invite.
Yeah i know what you mean but on mobile version it's taking me to club.ubisoft.com and when i click add friends white circle appears and nothing is happenining
I recieved my invite from a friend, and for me it didn't work through the mobile version.
I had to go to my PC to accept and arrange everything. Maybe it works the same for the invitation part of the thing?
Just my 2cents of course.
