YogaDNS not working correctly

Hi, 

I have different problems with the NextDNS app; installatoin fails to create Tap Device, and if I finally get it to install, it's unresponsive on the enable/disable options.

So I'm trying YogaDNS, configured with the wizard, I can see on the main screen all the queries resolved with NextDNS and it seems to work, but if I go on the my account page on NextDNS I can see the warning that I'm not using the service's dns. Also if I browse a page that I know is full of ads, I can see some of them (should be blocked with the Adguard filter on that profile). If I set dns on the NIC, everythins works, all ads blocked.

So it seems that the YogaDNS app is not working correctly.

What can I check?

Thank you!
