Mobile data restriction glitchy
Before the update mobile data restrictions worked perfectly. Now, I've noticed my son's data usage has increased. WiFi Assist has been disabled. When I checked his phone, apps I disabled for mobile data usage were switched on. So, I figured he figured out my code which of course he denied. Today, I had his phone and noticed that even though the restrictions settings were in place and working, just exiting and coming back to cellular data settings removes the restriction to not allow changes. Is there a way to fix this problem, or is it something they would catch in the next update?
