The shared Purchase DOES NOT WORK BOOUUUHHH!!!!

I buy Gaplus at $3.99 and expect with my apple family group that other will have access, but in fact....NO. This really SUCKS, can you imagine we are 5, this means I would have to pay 5 times 3.99. The game itself is good, but clearly if you buy it and want to share purchase....DO NOT BUY ITS A TRAP. Hope Namco will come with a solution/explanation. The game is not that bad, except move and fire could be optimized
