We're subscribers for the paid plan since december of last year and while the first 3-4 months everything was kinda working fine. From then until now it has been a plethora of problems of which the most prominents: - Parent app never managing to show with the web history - Parent app not updating with what actually the kids are using (real time or history) - Setting for blocked apps changing / not kicking in without user action - Plans to restrict access being enabled without user action (and the opposite) All in all, most of the problems seems to be related to syncing between the kids devices and parent's. At first I thought the teenager was messing around using one of us parent's device and changing his setting but now the changes are clearly not meant to be in his favour so the app even caused discussions and loss of trust between parents and kids. We have all android devices (nokia and samsungs) and the tablets are 2 kindle fire. It's not like we're having issue for some unknown device having problems. Just before renewing a month ago I got all the profile of the kids unlinked. Resetting all the links by inserting again the device code, restored them, but it's just another huge red flag of how, technically, this service is not reliable. If you want to be sure about the time your kids use their phones, take them away and explain them why / show them that there is other stuff to be done in your day, apart from staring at a screen. Also, buy a basic phone (they still exists, yes) so that, even if they try, they cannot really install anything on it due to hardware limitations.
