I have same problem in safe family regarding childs web browsing and seeing web history as everyone else:they are not working. In blocked content i even made specific pages to block list but it does not work. Browsing history shows that childs been "in this address" but when checked, theres only description about chrome and how wonderful it is. Now that mcafee family safe has gone to subscription only, it really would be nice for these features to work. Childs phone is Samsung Xcover 3 and parents phones are Oneplus 3 and Honor 7 lite.
what browsers are installed on your child's device? just chrome or are there others installed?
if possible can you provide the Android OS version that your kids are on?
to get this -> android settings -> about phone -> android version (this may not match exactly for your android devices).
There's Samsungs browser which is not used, and Chome and Google search app. Chrome and search app being the browsers used. Android version is 7.1.1.
Blocker seems to work now, don't know yet about allowed sites web history. Should there be some kind of way to see to whom child is texting with sms?
