I have it set on my Edge Router X for all devices on my network. Very straightforward to do.
On my phone at least you don't need an app to set it up, you can just designate the private DNS in the settings. This is probably also true for other devices but I haven't bothered looking into it.
That's what i've just tried to do (admittedly only on a trial account) but it's doing jack shit. Interface is saying I'm not connected to the DNS and ads are freeflowing.
