This app does NOT work if your child uses a Kindle Fire tablet. It totally hosed Google Play on both child's tablets and I had to change their birthdays to 1 day before 13 years old, then wait until their profiles "turned 13" so I could turn off Parent Supervision. I don't think a parent should be forced to use Parent Supervision just because they are under 13. I should be able to choose to turn off that feature regardless of their age. As soon as I repair Google Play Services on my Kindle, I am uninstalling this app forever.
