No,

The problem is i cannot send the promo item to the game because i cannot see my registered in game character in my square enix account.

When i go to square enix, additional services, enter the promo code, the only character i can see is “character” there for my character is nom existant. So i cannot send the promo item in the game at all.

Its really a bug square enix needs to fix in my account, not even the ingame gm could of helped me he said to ask for dev support here
