Bests & Worsts Reviews from Amazon

I purchase/unlocked everything onthis app on my kids fire tablet and added it to their kids content so they could play it on their profiles, but as many times as I delete the app, re install, re download, restore purchase,, and add it again everywhere, it WILL NOT TRANSFER UNLOCKED CONTENT TO KIDS PROFILE. Not real happy I spent money on an app my kids can't even enjoy.... It only shows as unlocked under my adult profile!
