Screentime has been a disaster since the latest iOS update. My child has lots of access he didn’t use to have. One of the biggest problems is that there is no longer a way to prevent the child from changing the time zone under Screentime (previously under location services) 
so now when downtime is on, he just changes the time zone and is on a mac till 3am. The only work around is to allow only 1 minute on any app and then grant requests all day long, which is a pain. All devices are up to date. I already turned screentime off and turned it back on again to no avail. Bring back this part of screentime so kids cannot get around downtime. See image. No option to control location services anymore on screentime.
