PS4 Sharing Packs between Family Members

This whole process of downloading packs and sharing across family members accounts on PS4 is hopeless.

I have downloaded a paid pack on my account so I manage everything. Then when the kids launch their own accounts they can't get access the packs. 

It then forces you to make a Microsoft Account which then links to their accounts which for me opens up all sorts of privacy issues. I can't work out why this is so complicated and poorly managed. 

 

Any help on how you can seamlessly share packs would be appreciated.
