Prohibit changing mobile data settings on child's device
Screen Time has an option to prohibit changes of the mobile data settings on the child's device. However it doesn't seem to work, or I misunderstand the idea.
Under Content & Privacy Restrictions I have Mobile Data Changes set to Don't Allow. However on my son's iPhone SE I still see that he can switch it off, enable connection sharing etc. If it's meant to be like that then what Mobile Data Changes parameter is intended for?
