Parental controls - lack of control...

I've reviewed the various questions about bugs in Apple's Parental Controls and can see numerous other people are having the same issues I am having - but none of the queries ends with a resolution. Have Apple fixed the bugs with their Parental Controls or given anyone a reasonable answer to explain what issues remain and whether they are looking to fix them? I have followed all of the advice given to everyone who has raised similar issues and the problems still persist. These being: Block at Downtime doesn't, App specific limits don't, some apps ignore Downtime altogether and this seems to change on a day to day basis. My kids may be figuring out some workarounds (like guessing the screen time passcode!) but I know that the issues listed above are not their doing because I've seen it happen whilst they haven't had access to their devices (as noted by several other users in these Communities). I've reset numerous times and it sometimes fixes some of the issues for a while, but they all come back - I've got better things to do with my time than reset these things over and over again for a few days 'Parental Control'. I'd spend less time physically checking their phone use directly. If these don't get fixed then the next phones my kids get won't be Apple ones. :(
