I have just installed safekids premium and want to schedule internet access times for my two girls. They use iphones ( Iphone 6s and SE2020) and i can not choose blocking of internet. I just have the possibility to choose between either “warning” or “statistics”… When customizing the same for the device Laptop , the blocking can be choosen! Whats wrong? in this case the app is useless! Please advise accordingly! thanks Oliver I
