Being asked to sign in to download app on child's iPad
I recently set up my child's iPad with their iCloud account and parental controls turned on. Everything has been fine until they tried to download an app. First we get asked for the passcode, which we know. Then we get asked to sign-in, but it only has a box for a password. I've tried using the password for my child's iCloud account and the password for my iCloud account, but neither works. I tried using the passcode again as well, but that didn't work. I have no idea what other "sign-in" it would be.
