Unavailable Features

So I purchased Family as a way to keep an eye on my children.  Surprised was I when I actually installed the software on their Apple Devices only to find out that the features Family promotes having available aren't even supported.  50% of the items aren't able to be used on the apple device.  It states Text Supervision, Social Network Supervision, Mobil App Supervision, & Time Supervision are all unavailable.  Items that offer assistance in helping our family watch for predators and keep our children safe aren't features that even work.  I wouldn't have purchased the product had I known that.  I have been a Norton customer for over ten years, Love Norton, just wish I would have known this.  Maybe I am missing something and have it set up incorrectly.
