I installed a new app on my daughters account on our Nexus 7 2013.
This app is blocked on start but entering Eset Parental Control settings I cannot find the app there.
If I choose unblock at app start and then press allow on the email that comes from that that doesn't help either.
This is the app:

It should be available for all ages, you use it to find books to loan from libraries so OK for all ages IMO.
