We have 2 Nintendo switches. I have a Nintendo account and my two kids who are under 13 have kid accounts under me on the family account.

I purchased breath of the wild digitally with my account. It is downloaded on both switches. With my account I can play it on either switch. My kids can only play it with their accounts on one of the switches (the primary switch, I guess).

This seems dumb. Why can't my kids use their account to play on both switches? I don't feel like I should have to buy a separate copy of the game for each family member
