I'm sorry, but that isn't enough. I have done that so many times. If you are already signed up for a tournament, and complete the convention card after registering, but before the tournament begins, the completed convention card will not show up. The only way I have been able to make the convention card show up is to de-register from the game, then invite your partner again. In my experience, this is the only way to have the c/c visible to others in the game. THIS IS NOT EXPLAINED in your instruction videos.
