DownTime and App Restrictions not working
My child's iPhone 6s is completely ignoring app restrictions (can't get YouTube to restrict at all, even when other apps seem to gray out during downtime). I've deleted apps, reloaded them, reset app restrictions and time limits, gone through the screen time settings a hundred times and now after I turned his phone off and back on to see if that fixed it, ALL the apps are available to use, even though it's 11:09pm anc his down time starts at 9pm thru 8am. We have iOS15.7.3 and are up to date with software currently. I don't think I'm the only one with this issue. What to do?? And please don't anyone tell me how to set up screen time restrictions and app restrictions--I've done all this and I KNOW how to do all this--it just ain't working people. And YouTube is the one app I need to restrict! Thanks
