Why can't I COMPLETELY restrict mobile data and Wi-Fi access to an app?

[j229]

Earlier I was using OnePlus where there is a possibility of COMPLETELY blocking internet access for any particular app. I am NOT talking about data usage in background. I could select a particular app -> restrict mobile data and/or wifi access. Also, there is an option to toggle background internet access.

Currently, I have Galaxy A50s with Android 10 (One UI 2.0). I have no way to completely block internet access for an app. There are a few options I found however, they all either require root or install VPN.

Why has Samsung removed such a native feature that is available in stock Android??

Am I missing something? Can anyone help me here?

Cheers!!

My Norton security has just introduced a feature about which apps are data harvesting, or have suspicious permissions, & the calculator appeared among a bunch of others! Permissions manager says none allowed & none denied but when I checked it has full network control of my phone! WTF?! All these things you can't uninstall now like Android Auto - Google AND Samsung are getting worse. I just bought an S23 and really wish I hadn't after reading this thread

you can just check whether it is permitted to use WIFI or data and you cannot restrict both of them

I figured this out on my own, but it doesnt work. My kids have phones with like 500 mb of data but I only.want them using data for certain apps. Right now they are not using any as I have wifi and mobile off.  The method you wrote about, when using the little.games.they play still throw up ads but when everything is off ads are off too

That does not work. It is not an option. can't uncheck both boxes.
