People have said you can manage it on the kids' device directly by logging in with your AppleId, but that doesn't help me if my kid is out and messages me asking me to allow an app or give her an extra half hour of screentime or something.
Parent mentions Google family link, whih can be setup and managed from litteraly everywhere. There's an iOS app and a fully functional website, so you can have no other android device than your kids, and still control everything.
Your kid can be visiting their grand parents and ask you to authorize some purchase or extra screen time, you'll be able to do it from your Windows computer.
That's the standard iOS' parental control is compared to.
Parenting controls still have a long way to go on Apple devices, but still it's miles ahead of other stuff (looking at you Netflix/Disney Plus).
But, IDK, maybe they got rid of that feature. Definitely used to be able to do that.
That's actually your choice if it's your choice whether/which apps they can install.
Had this happen to us, my partners kids. Its a subtle attempt to destabilize and subvert her authority as parent figure even though old mate isn't even around, hasn't been for years and still is an abusive S*t. We got forced to buy a iphone in order to put parent restrictions on. Its shits as. I hate apple. Company does bulk crap that enables abusers and does piss all to prevent it or be like hey...maybe this is a ethically shit thing to implement. Maybe its gonna cause a whole host of people grief. Don't even get me started on apple air tags.
I've put in numerous bug reports on parental controls to Apple, I'm 0/9 on fixes.
"If your phone has bad reception, it's because you're holding it wrong. Why would you hold it like that?"
Especially if the children are young enough that you need to use parental controls.
