I’m asking for Android specifically, but I’m curious what else is out there.
For example, some apps work without internet but may use it if it’s available. I might want to block that without having to turn off wifi, force stopping it, and wiping the cache/data.
Similarly, maybe I only want to use the app over a VPN and want to prevent accidentally opening it without first turning the VPN on.
In the picture its blocking the internet for a single app - that app being “blinkist”. You mean you want to block Google Play only?
Oh, I see! I missed that. Is it possible to block the Internet to Google Play Services?
No, I think that is a whole different kind of “system”. Download the app and test it out :)
